In an AIM7 test, this commit degraded\nperformance by about 40%.\n\nThe commit runs rcu callbacks in a kthread instead of softirq. We observed\nhigh rate of context switch which is caused by this. Out test system has\n64 CPUs and HZ is 1000, so we saw more than 64k context switch per second\nwhich is caused by RCU\u0027s per-CPU kthread. A trace showed that most of\nthe time the RCU per-CPU kthread doesn\u0027t actually handle any callbacks,\nbut instead just does a very small amount of work handling grace periods.\nThis means that RCU\u0027s per-CPU kthreads are making the scheduler do quite\na bit of work in order to allow a very small amount of RCU-related\nprocessing to be done.\n\nAlex Shi\u0027s analysis determined that this slowdown is due to lock\ncontention within the scheduler. Unfortunately, as Peter Zijlstra points\nout, the scheduler\u0027s real-time semantics require global action, which\nmeans that this contention is inherent in real-time scheduling. (Yes,\nperhaps someone will come up with a workaround -- otherwise, -rt is not\ngoing to do well on large SMP systems -- but this patch will work around\nthis issue in the meantime. And \"the meantime\" might well be forever.)\n\nThis patch therefore re-introduces softirq processing to RCU, but only\nfor core RCU work. RCU callbacks are still executed in kthread context,\nso that only a small amount of RCU work runs in softirq context in the\ncommon case. This should minimize ksoftirqd execution, allowing us to\nskip boosting of ksoftirqd for CONFIG_RCU_BOOST\u003dy kernels.\n\nSigned-off-by: Shaohua Li \u003cshaohua.li@intel.com\u003e\nTested-by: \"Alex,Shi\" \u003calex.shi@intel.com\u003e\nSigned-off-by: Paul E.

Hence we can lift the inode_lock from\nprune_icache as well.\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "5818fcc8bd1b27af4d40b8357b91a56cc3fae6a4", "tree": "c2f266e82306fa98c78130b0dc79ef9716d3c9c7", "parents": [ "0625bef6060fab4aab0e484130b59af5e9ac81bc", "117a91e0f25fd7698e20ac3dfa62086be3dc82a3" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 24 08:02:21 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 24 08:02:21 2011 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/pkl/squashfs-linus\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/pkl/squashfs-linus:\n Squashfs: Use vmalloc rather than kmalloc for zlib workspace\n Squashfs: handle corruption of directory structure\n Squashfs: wrap squashfs_mount() definition\n Squashfs: xz_wrapper doesn\u0027t need to include squashfs_fs_i.h anymore\n Squashfs: Update documentation to include compression options\n Squashfs: Update Kconfig help text to include xz compression\n Squashfs: add compression options support to xz decompressor\n Squashfs: extend decompressor framework to handle compression options\n" }, { "commit": "1b506cfb6ae63f352643d6e208c85c1351547036", "tree": "4556cbdb0443eadc4406778a45d7b771f0dc7be7", "parents": [ "4cc4d24efce4672f9b0e7fa27963770ae602998f", "a49fb4c3d035ab516507b31ec3bd49263caee14d" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 24 07:57:38 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 24 07:57:38 2011 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.open-osd.org/linux-open-osd\n\n* \u0027for-linus\u0027 of git://git.open-osd.org/linux-open-osd:\n exofs: deprecate the commands pending counter\n exofs: Write sbi-\u003es_nextid as part of the Create command\n exofs: Add option to mount by osdname\n exofs: Override read-ahead to align on stripe_size\n exofs: simple fsync race fix\n exofs: Optimize read_4_write\n exofs: Trivial: fix some indentation and debug prints\n exofs: Remove redundant unlikely()\n" }, { "commit": "da23ef0549d4205ca9b576cf6cce9a80d0c3e43a", "tree": "476939ca9c146ebc20ac627098690b1e2026827a", "parents": [ "7a9730af9c596749425a98eba136152e5be4602a" ], "author": { "name": "Stuart Swales", "email": "stuart.swales.croftnuisk@gmail.com", "time": "Tue Mar 22 16:35:06 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Mar 22 17:44:17 2011 -0700" }, "message": "adfs: add hexadecimal filetype suffix option\n\nADFS (FileCore) storage complies with the RISC OS filetype specification\n(12 bits of file type information is stored in the file load address,\nrather than using a file extension).

If successful, it\nshould return the vfsmount struct it creates (which it should also have added\nto the namespace using do_add_mount() or similar). If there\u0027s a collision with\nanother automount attempt, NULL should be returned. If the directory specified\nby the parameter should be used directly rather than being mounted upon,\n-EISDIR should be returned. In any other case, an error code should be\nreturned.\n\nThe -\u003ed_automount() operation is called with no locks held and may sleep. At\nthis point the pathwalk algorithm will be in ref-walk mode.\n\nWithin fs/namei.c itself, a new pathwalk subroutine (follow_automount()) is\nadded to handle mountpoints. It will return -EREMOTE if the automount flag was\nset, but no d_automount() op was supplied, -ELOOP if we\u0027ve encountered too many\nsymlinks or mountpoints, -EISDIR if the walk point should be used without\nmounting and 0 if successful. The path will be updated to point to the mounted\nfilesystem if a successful automount took place.\n\n__follow_mount() is replaced by follow_managed() which is more generic\n(especially with the patch that adds -\u003ed_manage()). This handles transits from\ndirectories during pathwalk, including automounting and skipping over\nmountpoints (and holding processes with the next patch).\n\n__follow_mount_rcu() will jump out of RCU-walk mode if it encounters an\nautomount point with nothing mounted on it.\n\nfollow_dotdot*() does not handle automounts as you don\u0027t want to trigger them\nwhilst following \"..\".\n\nI\u0027ve also extracted the mount/don\u0027t-mount logic from autofs4 and included it\nhere. It makes the mount go ahead anyway if someone calls open() or creat(),\ntries to traverse the directory, tries to chdir/chroot/etc. into the directory,\nor sticks a \u0027/\u0027 on the end of the pathname. If they do a stat(), however,\nthey\u0027ll only trigger the automount if they didn\u0027t also say O_NOFOLLOW.\n\nI\u0027ve also added an inode flag (S_AUTOMOUNT) so that filesystems can mark their\ninodes as automount points. This flag is automatically propagated to the\ndentry as DCACHE_NEED_AUTOMOUNT by __d_instantiate(). This saves NFS and could\nsave AFS a private flag bit apiece, but is not strictly necessary. It would be\npreferable to do the propagation in d_set_d_op(), but that doesn\u0027t normally\nhave access to the inode.\n\n[AV: fixed breakage in case if __follow_mount_rcu() fails and nameidata_drop_rcu()\nsucceeds in RCU case of do_lookup(); we need to fall through to non-RCU case after\nthat, rather than just returning with ungrabbed *path]\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nWas-Acked-by: Ian Kent \u003craven@themaw.net\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "18bce371ae09af6c20ee62c1092a4d1d0e84dd49", "tree": "f3467fafd8e49392e3f6efef7b88a7b4dd3b7b06", "parents": [ "ec08bdb148767f1193f5f3028749ed865ac27181", "a8f2800b4f7b76cecb7209cb6a7d2b14904fc711" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jan 14 13:17:26 2011 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jan 14 13:17:26 2011 -0800" }, "message": "Merge branch \u0027for-2.6.38\u0027 of git://linux-nfs.org/~bfields/linux\n\n* \u0027for-2.6.38\u0027 of git://linux-nfs.org/~bfields/linux: (62 commits)\n nfsd4: fix callback restarting\n nfsd: break lease on unlink, link, and rename\n nfsd4: break lease on nfsd setattr\n nfsd: don\u0027t support msnfs export option\n nfsd4: initialize cb_per_client\n nfsd4: allow restarting callbacks\n nfsd4: simplify nfsd4_cb_prepare\n nfsd4: give out delegations more quickly in 4.1 case\n nfsd4: add helper function to run callbacks\n nfsd4: make sure sequence flags are set after destroy_session\n nfsd4: re-probe callback on connection loss\n nfsd4: set sequence flag when backchannel is down\n nfsd4: keep finer-grained callback status\n rpc: allow xprt_class-\u003esetup to return a preexisting xprt\n rpc: keep backchannel xprt as long as server connection\n rpc: move sk_bc_xprt to svc_xprt\n nfsd4: allow backchannel recovery\n nfsd4: support BIND_CONN_TO_SESSION\n nfsd4: modify session list under cl_lock\n Documentation: fl_mylease no longer exists\n ...\n\nFix up conflicts in fs/nfsd/vfs.c with the vfs-scale work.

This is called rcu-walk, as opposed to the current\nalgorithm which is a refcount based walk, or ref-walk.\n\nThis results in far fewer atomic operations on every path element,\nsignificantly improving path lookup performance. It also avoids cacheline\nbouncing on common dentries, significantly improving scalability.\n\nThe overall design is like this:\n* LOOKUP_RCU is set in nd-\u003eflags, which distinguishes rcu-walk from ref-walk.\n* Take the RCU lock for the entire path walk, starting with the acquiring\n of the starting path (eg. root/cwd/fd-path). So now dentry refcounts are\n not required for dentry persistence.\n* synchronize_rcu is called when unregistering a filesystem, so we can\n access d_ops and i_ops during rcu-walk.\n* Similarly take the vfsmount lock for the entire path walk. So now mnt\n refcounts are not required for persistence. Also we are free to perform mount\n lookups, and to assume dentry mount points and mount roots are stable up and\n down the path.\n* Have a per-dentry seqlock to protect the dentry name, parent, and inode,\n so we can load this tuple atomically, and also check whether any of its\n members have changed.\n* Dentry lookups (based on parent, candidate string tuple) recheck the parent\n sequence after the child is found in case anything changed in the parent\n during the path walk.\n* inode is also RCU protected so we can load d_inode and use the inode for\n limited things.\n* i_mode, i_uid, i_gid can be tested for exec permissions during path walk.\n* i_op can be loaded.\n\nWhen we reach the destination dentry, we lock it, recheck lookup sequence,\nand increment its refcount and mountpoint refcount. RCU and vfsmount locks\nare dropped. This is termed \"dropping rcu-walk\". If the dentry refcount does\nnot match, we can not drop rcu-walk gracefully at the current point in the\nlokup, so instead return -ECHILD (for want of a better errno). This signals the\npath walking code to re-do the entire lookup with a ref-walk.\n\nAside from the final dentry, there are other situations that may be encounted\nwhere we cannot continue rcu-walk. In that case, we drop rcu-walk (ie. take\na reference on the last good dentry) and continue with a ref-walk. Again, if\nwe can drop rcu-walk gracefully, we return -ECHILD and do the whole lookup\nusing ref-walk. But it is very important that we can continue with ref-walk\nfor most cases, particularly to avoid the overhead of double lookups, and to\ngain the scalability advantages on common path elements (like cwd and root).\n\nThe cases where rcu-walk cannot continue are:\n* NULL dentry (ie. any uncached path element)\n* parent with d_inode-\u003ei_op-\u003epermission or ACLs\n* dentries with d_revalidate\n* Following links\n\nIn future patches, permission checks and d_revalidate become rcu-walk aware. It\nmay be possible eventually to make following links rcu-walk aware.\n\nUncached path elements will always require dropping to ref-walk mode, at the\nvery least because i_mutex needs to be grabbed, and objects allocated.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n" }, { "commit": "fa0d7e3de6d6fc5004ad9dea0dd6b286af8f03e9", "tree": "203e0f73883e4c26b5597e36042386a1237dab35", "parents": [ "77812a1ef139d84270d27faacc0630c887411013" ], "author": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Fri Jan 07 17:49:49 2011 +1100" }, "committer": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Fri Jan 07 17:50:26 2011 +1100" }, "message": "fs: icache RCU free inodes\n\nRCU free the struct inode. This will allow:\n\n- Subsequent store-free path walking patch. The inode must be consulted for\n permissions when walking, so an RCU inode reference is a must.\n- sb_inode_list_lock to be moved inside i_lock because sb list walkers who want\n to take i_lock no longer need to take sb_inode_list_lock to walk the list in\n the first place. This will simplify and optimize locking.\n- Could remove some nested trylock loops in dcache code\n- Could potentially simplify things a bit in VM land. Do not need to take the\n page lock to follow page-\u003emapping.\n\nThe downsides of this is the performance cost of using RCU. In a simple\ncreat/unlink microbenchmark, performance drops by about 10% due to inability to\nreuse cache-hot slab objects. As iterations increase and RCU freeing starts\nkicking over, this increases to about 20%.\n\nIn cases where inode lifetimes are longer (ie. many inodes may be allocated\nduring the average life span of a single inode), a lot of this cache reuse is\nnot applicable, so the regression caused by this patch is smaller.\n\nThe cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU,\nhowever this adds some complexity to list walking and store-free path walking,\nso I prefer to implement this at a later date, if it is shown to be a win in\nreal situations.

initialization\n\nWhen the lazy_itable_init extended option is passed to mke2fs, it\nconsiderably speeds up filesystem creation because inode tables are\nnot zeroed out. The fact that parts of the inode table are\nuninitialized is not a problem so long as the block group descriptors,\nwhich contain information regarding how much of the inode table has\nbeen initialized, has not been corrupted However, if the block group\nchecksums are not valid, e2fsck must scan the entire inode table, and\nthe the old, uninitialized data could potentially cause e2fsck to\nreport false problems.\n\nHence, it is important for the inode tables to be initialized as soon\nas possble. This commit adds this feature so that mke2fs can safely\nuse the lazy inode table initialization feature to speed up formatting\nfile systems.\n\nThis is done via a new new kernel thread called ext4lazyinit, which is\ncreated on demand and destroyed, when it is no longer needed. There\nis only one thread for all ext4 filesystems in the system. When the\nfirst filesystem with inititable mount option is mounted, ext4lazyinit\nthread is created, then the filesystem can register its request in the\nrequest list.\n\nThis thread then walks through the list of requests picking up\nscheduled requests and invoking ext4_init_inode_table(). Next schedule\ntime for the request is computed by multiplying the time it took to\nzero out last inode table with wait multiplier, which can be set with\nthe (init_itable\u003dn) mount option (default is 10). We are doing\nthis so we do not take the whole I/O bandwidth. When the thread is no\nlonger necessary (request list is empty) it frees the appropriate\nstructures and exits (and can be created later later by another\nfilesystem).\n\nWe do not disturb regular inode allocations in any way, it just do not\ncare whether the inode table is, or is not zeroed. But when zeroing, we\nhave to skip used inodes, obviously. Also we should prevent new inode\nallocations from the group, while zeroing is on the way. For that we\ntake write alloc_sem lock in ext4_init_inode_table() and read alloc_sem\nin the ext4_claim_inode, so when we are unlucky and allocator hits the\ngroup which is currently being zeroed, it just has to wait.\n\nThis can be suppresed using the mount option no_init_itable.\n\nSigned-off-by: Lukas Czerner \u003clczerner@redhat.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "03f890f8c2f5c9008d3d8f6d85267717ced4bd79", "tree": "0e61bcc8e94152ef85ccb402868966adb8d44c40", "parents": [ "b40d4f84becd69275451baee7f0801c85eb58437" ], "author": { "name": "Nikanth Karthikesan", "email": "knikanth@suse.de", "time": "Wed Oct 27 15:34:11 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Oct 27 18:03:13 2010 -0700" }, "message": "/proc/pid/pagemap: document in Documentation/filesystems/proc.txt\n\nDocument /proc/pid/pagemap in Documentation/filesystems/proc.txt\n\nSigned-off-by: Nikanth Karthikesan \u003cknikanth@suse.de\u003e\nCc: Richard Guenther \u003crguenther@suse.de\u003e\nCc: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nAcked-by: Matt Mackall \u003cmpm@selenic.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b40d4f84becd69275451baee7f0801c85eb58437", "tree": "78258f7b431a900bf8292d25970dea74b8aa283f", "parents": [ "d16e15f5b029fc7d03540ba0e5fb23b0abb0ebe0" ], "author": { "name": "Nikanth Karthikesan", "email": "knikanth@suse.de", "time": "Wed Oct 27 15:34:10 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Oct 27 18:03:13 2010 -0700" }, "message": "/proc/pid/smaps: export amount of anonymous memory in a mapping\n\nExport the number of anonymous pages in a mapping via smaps.\n\nEven the private pages in a mapping backed by a file, would be marked as\nanonymous, when they are modified.

Jiri\nSladby points out that the tty structure we\u0027re using may already be\ngone, and Al Viro doesn\u0027t hold back in complaining about the random\nloading of \u0027filp-\u003eprivate_data\u0027 which doesn\u0027t have to be a pointer at\nall, nor does checking the magic field for TTY_MAGIC prove anything.\n\nBelated review by Al:\n\n \"a) global variable depending on stdin of the last opener? Affecting\n output of read(2)? Really?\n\n b) iterator is broken; list should be locked in -\u003estart(), unlocked in\n -\u003estop() and *NOT* unlocked/relocked in -\u003enext()\n\n c) -\u003eshow() ought to do nothing in case of -\u003edevice \u003d\u003d NULL, instead\n of skipping those in -\u003enext()/-\u003estart()\n\n d) regardless of the merits of the bright idea about asterisk at that\n line in output *and* regardless of (a), the implementation is not\n only atrociously ugly, it\u0027s actually very likely to be a roothole.\n Verifying that Cthulhu knows what number happens to be address of a\n tty_struct by blindly dereferencing memory at that address...\n Ouch.\n\n Please revert that crap.\"\n\nAnd Christoph pipes in and NAK\u0027s the approach of walking fd tables etc\ntoo.
