It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here.

Prior to that patch, that caused the client to fall\nback to doing a normal lookup. When that patch went in, the code began\nreturning that error to userspace. The d_revalidate codepath however\nnever had the corresponding change, so it was still possible to end up\nwith a NULL ctx-\u003estate pointer after that.\n\nThat patch caused a regression. When we attempt to open a directory that\ndoes not have a cached dentry, that open now errors out with EISDIR. If\nyou attempt the same open with a cached dentry, it will succeed.\n\nFix this by reverting the change in nfs_atomic_lookup and allowing\nattempts to open directories to fall back to a normal lookup\n\nAlso, add a NFSv4-specific f_ops-\u003eopen routine that just returns\n-ENOTDIR. This should never be called if things are working properly,\nbut if it ever is, then the dprintk may help in debugging.\n\nTo facilitate this, a new file_operations field is also added to the\nnfs_rpc_ops struct.\n\nCc: stable@kernel.org\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "bfe8684869601dacfcb2cd69ef8cfd9045f62170", "tree": "4e213aaa766b26f43f0f9ec7998a7745239d9377", "parents": [ "6d6b77f163c7eabedbba00ed2abb7d4a570bff76" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Fri Oct 28 14:13:29 2011 +0200" }, "committer": { "name": "Christoph Hellwig", "email": "hch@serles.lst.de", "time": "Wed Nov 02 12:53:43 2011 +0100" }, "message": "filesystems: add set_nlink()\n\nReplace remaining direct i_nlink updates with a new set_nlink()\nupdater function.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nTested-by: Toshiyuki Okajima \u003ctoshi.okajima@jp.fujitsu.com\u003e\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\n" }, { "commit": "6d6b77f163c7eabedbba00ed2abb7d4a570bff76", "tree": "6ce074a7dd5a25fae28ef9de6f59ddee08ea4e61", "parents": [ "dd2a981f46a0903a8770a784f213d4d40bbb6f19" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Fri Oct 28 14:13:28 2011 +0200" }, "committer": { "name": "Christoph Hellwig", "email": "hch@serles.lst.de", "time": "Wed Nov 02 12:53:43 2011 +0100" }, "message": "filesystems: add missing nlink wrappers\n\nReplace direct i_nlink updates with the respective updater function\n(inc_nlink, drop_nlink, clear_nlink, inode_dec_link_count).\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\n" }, { "commit": "a9a4a87a5942e9271523197a90aaa82349c818fb", "tree": "88001fc58944798ff41d36a08ccf2bdace2cda6e", "parents": [ "919066d690541f4bd727b0e0fc2f7a20a7e3b3a7" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Mon Oct 17 16:08:46 2011 -0700" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Tue Oct 18 09:14:34 2011 -0700" }, "message": "NFS: Use the inode-\u003ei_version to cache NFSv4 change attribute information\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "3d4ff43d895c50319af45eb4bf04a4618eccdf76", "tree": "b412cd076920a903a854a20bceed4a0ce511fd13", "parents": [ "82a2c1b77ada3b81911deeb871719ec5ff77f83c" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Jun 22 18:40:12 2011 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Jul 20 01:43:44 2011 -0400" }, "message": "nfs_open_context doesn\u0027t need struct path either\n\njust dentry, please...\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "533eb4611c9eea53072eb6a61d5a6393b6a77ed7", "tree": "adb2b4cbfe85689979d2cf971b65ebcd0d383d56", "parents": [ "1d92a08da23848a38eece4df7eaa4e8ec0e6c699" ], "author": { "name": "Andy Adamson", "email": "andros@netapp.com", "time": "Mon Jun 13 18:25:56 2011 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jun 15 11:24:29 2011 -0400" }, "message": "NFSv4.1: allow nfs_fhget to succeed with mounted on fileid\n\nCommit 28331a46d88459788c8fca72dbb0415cd7f514c9 \"Ensure we request the\nordinary fileid when doing readdirplus\"\nchanged the meaning of NFS_ATTR_FATTR_FILEID which used to be set when\nFATTR4_WORD1_MOUNTED_ON_FILED was requested.\n\nAllow nfs_fhget to succeed with only a mounted on fileid when crossing\na mountpoint or a referral.\n\nAsk for the fileid of the absent file system if mounted_on_fileid is not\nsupported.\n\nSigned-off-by: Andy Adamson \u003candros@netapp.com\u003e\ncc:stable@kernel.org [2.6.39]\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "0f66b5984df2fe1617c05900a39a7ef493ca9de9", "tree": "682ad324d9cfab94ffde805c6ca0372f7f40d3d3", "parents": [ "0b760113a3a155269a3fba93a409c640031dd68f" ], "author": { "name": "Peng Tao", "email": "bergwolf@gmail.com", "time": "Sat Oct 16 22:07:46 2010 -0700" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jun 15 11:24:28 2011 -0400" }, "message": "NFS41: do not update isize if inode needs layoutcommit\n\nnfs_update_inode will update isize if there is no queued pages.

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.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7.

CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "b4d2314bb88b07e5a04e6c75b442a1dfcd60e340", "tree": "9727944bf30a47cf02f9b9547adcaeafeee25843", "parents": [ "49697ee79242d5f8ac88f1ebc62e583d16bcc687" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Mar 10 15:21:44 2010 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Mar 10 15:21:44 2010 -0500" }, "message": "NFSv4: Don\u0027t ignore the NFS_INO_REVAL_FORCED flag in nfs_revalidate_inode()\n\nIf the NFS_INO_REVAL_FORCED flag is set, that means that we don\u0027t yet have\nan up to date attribute cache.

Also, this may\nlead to sub-optimal block allocations in the underlying file\nsystem on the server. This may cause the read throughputs to\nbe reduced when reading the file from the server.\n\nPeter: There has been a lot of work recently done to address out of\norder issues on a systemic level. However, the NFS client is\nstill susceptible to the problem.
