This is\nbecause a bunch of people call mark_inode_dirty, which is void so we can\u0027t\nreturn ENOSPC. This needs to be fixed in a few areas\n\n1) file_update_time - this updates the mtime and such when writing to a file,\nwhich will call mark_inode_dirty. So copy file_update_time into btrfs so we can\ncall btrfs_dirty_inode directly and return an error if we get one appropriately.\n\n2) fix symlinks to use btrfs_setattr for -\u003esetattr. For some reason we weren\u0027t\nsetting -\u003esetattr for symlinks, even though we should have been. This catches\none of the cases where we were getting errors in mark_inode_dirty.\n\n3) Fix btrfs_setattr and btrfs_setsize to call btrfs_dirty_inode directly\ninstead of mark_inode_dirty. This lets us return errors properly for truncate\nand chown/anything related to setattr.\n\n4) Add a new btrfs_fs_dirty_inode which will just call btrfs_dirty_inode and\nprint an error if we have one. The only remaining user we can\u0027t control for\nthis is touch_atime(), but we don\u0027t really want to keep people from walking\ndown the tree if we don\u0027t have space to save the atime update, so just complain\nbut don\u0027t worry about it.\n\nWith this patch xfstests 83 complains a handful of times instead of hundreds of\ntimes.

Independent processes\naccessing the same file synchronize over a single lock, even though\nthey have no need for synchronization at all.\n\nUnder high utilization this can cause llseek to scale very poorly on larger\nsystems.\n\nThis patch does some rethinking of the llseek locking model:\n\nFirst the 64bit f_pos is not necessarily atomic without locks\non 32bit systems. This can already cause races with read() today.\nThis was discussed on linux-kernel in the past and deemed acceptable.\nThe patch does not change that.\n\nLet\u0027s look at the different seek variants:\n\nSEEK_SET: Doesn\u0027t really need any locking.\nIf there\u0027s a race one writer wins, the other loses.\n\nFor 32bit the non atomic update races against read()\nstay the same. Without a lock they can also happen\nagainst write() now. The read() race was deemed\nacceptable in past discussions, and I think if it\u0027s\nok for read it\u0027s ok for write too.\n\n\u003d\u003e Don\u0027t need a lock.\n\nSEEK_END: This behaves like SEEK_SET plus it reads\nthe maximum size too. Reading the maximum size would have the\n32bit atomic problem. But luckily we already have a way to read\nthe maximum size without locking (i_size_read), so we\ncan just use that instead.\n\nWithout i_mutex there is no synchronization with write() anymore,\nhowever since the write() update is atomic on 64bit it just behaves\nlike another racy SEEK_SET.

So replace the\ntrans_mutex with a trans_lock spinlock and use it to do the following\n\n1) Protect fs_info-\u003erunning_transaction. All trans handles have to do is check\nthis, and then take a reference of the transaction and keep on going.\n2) Protect the fs_info-\u003etrans_list. This doesn\u0027t get used too much, basically\nit just holds the current transactions, which will usually just be the currently\ncommitting transaction and the currently running transaction at most.\n3) Protect the dead roots list. This is only ever processed by splicing the\nlist so this is relatively simple.\n4) Protect the fs_info-\u003ereloc_ctl stuff. This is very lightweight and was using\nthe trans_mutex before, so this is a pretty straightforward change.\n5) Protect fs_info-\u003eno_trans_join. Because we don\u0027t hold the trans_lock over\nthe entirety of the commit we need to have a way to block new people from\ncreating a new transaction while we\u0027re doing our work. So we set no_trans_join\nand in join_transaction we test to see if that is set, and if it is we do a\nwait_on_commit.\n6) Make the transaction use count atomic so we don\u0027t need to take locks to\nmodify it when we\u0027re dropping references.\n7) Add a commit_lock to the transaction to make sure multiple people trying to\ncommit the same transaction don\u0027t race and commit at the same time.\n8) Make open_ioctl_trans an atomic so we don\u0027t have to take any locks for ioctl\ntrans.\n\nI have tested this with xfstests, but obviously it is a pretty hairy change so\nlots of testing is greatly appreciated.

running.\n\n3) writepage:\n __extent_writepage\n btrfs_writepage_end_io_hook\n\nPages are cirtical resourses and produce a lot of corner cases during writeback,\nso it is valuable to know how page is

reference and cow:\n\tbtrfs_delayed_tree_ref\n\tbtrfs_delayed_data_ref\n\tbtrfs_delayed_ref_head\n\tbtrfs_cow_block\n\nBtrfs natively supports back references, these tracepoints are helpful

The result was btrfs_file_write\nlooping forever retrying the iov_iter_copy_from_user_atomic\n\nWe deal with this by changing btrfs_file_write to drop down to single\npage copies when iov_iter_copy_from_user_atomic starts returning failure.\n\n2) The btrfs_file_write code was leaking delalloc reservations when\niov_iter_copy_from_user_atomic returned zero. The looping above would\nresult in the entire filesystem running out of delalloc reservations and\nconstantly trying to flush things to disk.\n\n3) btrfs_file_write will lock down page cache pages, make sure\nany writeback is finished, do the copy_from_user and then release them.\nBefore the loop runs we check the first and last pages in the write to\nsee if they are only being partially modified. If the start or end of\nthe write isn\u0027t aligned, we make sure the corresponding pages are\nup to date so that we don\u0027t introduce garbage into the file.\n\nWith the copy_from_user changes, we\u0027re allowing the VM to reclaim the\npages after a partial update from copy_from_user, but we\u0027re not\nmaking sure the page cache page is up to date when we loop around to\nresume the write.\n\nWe deal with this by pushing the up to date checks down into the page\nprep code.

And also disable page fault in critical region in\nbtrfs_copy_from_user().\n\nReviewed-by: Yan, Zheng\u003czheng.z.yan@intel.com\u003e\nSigned-off-by: Zhong, Xin \u003cxin.zhong@intel.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "495e86779f4f319828bc10dfc0c9ac2161868077", "tree": "62729f2b65c9565fadb551bd8d343d6c57d7cb85", "parents": [ "6a912213046ecb6511fdf35531a0c7de3de963c9" ], "author": { "name": "Josef Bacik", "email": "josef@redhat.com", "time": "Fri Nov 19 20:36:10 2010 +0000" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Sun Nov 21 22:26:09 2010 -0500" }, "message": "Btrfs: hold i_mutex when calling btrfs_log_dentry_safe\n\nSince we walk up the path logging all of the parts of the inode\u0027s path, we need\nto hold i_mutex to make sure that the inode is not renamed while we\u0027re logging\neverything. btrfs_log_dentry_safe does dget_parent and all of that jazz, but we\nmay get unexpected results if the rename changes the inode\u0027s location while\nwe\u0027re higher up the path logging those dentries, so do this for safety reasons.\nThanks,\n\nSigned-off-by: Josef Bacik \u003cjosef@redhat.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "b25b550bb153626df6a48eb8583e923e3dfcf64a", "tree": "baca9843877b8b3a254cde92ac2a9072014b5621", "parents": [ "eda054770e5cd0e9ee1568dfcbcf39f9ade4f545", "6f902af400b2499c80865c62a06fbbd15cf804fd" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 11 14:18:47 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 11 14:18:47 2010 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable:\n Btrfs: The file argument for fsync() is never null\n Btrfs: handle ERR_PTR from posix_acl_from_xattr()\n Btrfs: avoid BUG when dropping root and reference in same transaction\n Btrfs: prohibit a operation of changing acl\u0027s mask when noacl mount option used\n Btrfs: should add a permission check for setfacl\n Btrfs: btrfs_lookup_dir_item() can return ERR_PTR\n Btrfs: btrfs_read_fs_root_no_name() returns ERR_PTRs\n Btrfs: unwind after btrfs_start_transaction() errors\n Btrfs: btrfs_iget() returns ERR_PTR\n Btrfs: handle kzalloc() failure in open_ctree()\n Btrfs: handle error returns from btrfs_lookup_dir_item()\n Btrfs: Fix BUG_ON for fs converted from extN\n Btrfs: Fix null dereference in relocation.c\n Btrfs: fix remap_file_pages error\n Btrfs: uninitialized data is check_path_shared()\n Btrfs: fix fallocate regression\n Btrfs: fix loop device on top of btrfs\n" }, { "commit": "6f902af400b2499c80865c62a06fbbd15cf804fd", "tree": "9bd7ee1dd243b5513ebad74b2870950a6d427d3c", "parents": [ "834e74759a473f8101a273e843d1edec2778801d" ], "author": { "name": "Dan Carpenter", "email": "error27@gmail.com", "time": "Sat May 29 09:49:07 2010 +0000" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Fri Jun 11 15:57:40 2010 -0400" }, "message": "Btrfs: The file argument for fsync() is never null\n\nThe \"file\" argument for fsync is never null so we can remove this check.\n\nWhat drew my attention here is that 7ea8085910e: \"drop unused dentry\nargument to -\u003efsync\" introduced an unconditional dereference at the\nstart of the function and that generated a smatch warning.\n\nSigned-off-by: Dan Carpenter \u003cerror27@gmail.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "058a457ef0ce28d595af53d6103db73332383cbc", "tree": "7f17117d57c90839cd6d50e588cba0bca97a0de6", "parents": [ "0e4dcbef1c0c3e29f9c7f824359445d385b2649a" ], "author": { "name": "Miao Xie", "email": "miaox@cn.fujitsu.com", "time": "Thu May 20 07:21:50 2010 +0000" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Fri Jun 11 11:46:12 2010 -0400" }, "message": "Btrfs: fix remap_file_pages error\n\nwhen we use remap_file_pages() to remap a file, remap_file_pages always return\nerror.

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. Build test were done on the following configurations and failures\n were fixed. 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": "441f4058a04b2943685ff94e0f5f1992b0b3649e", "tree": "80a61f6dddcf7d5831a8bd3771ffa2b430af3935", "parents": [ "7c34691abe23741bfc7d2514efd5a39f0e0ecb06", "8ad6fcab564c5bc956bdc3dfa440ab152b6e780f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 18 16:50:55 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 18 16:50:55 2010 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable: (30 commits)\n Btrfs: fix the inode ref searches done by btrfs_search_path_in_tree\n Btrfs: allow treeid\u003d\u003d0 in the inode lookup ioctl\n Btrfs: return keys for large items to the search ioctl\n Btrfs: fix key checks and advance in the search ioctl\n Btrfs: buffer results in the space_info ioctl\n Btrfs: use __u64 types in ioctl.h\n Btrfs: fix search_ioctl key advance\n Btrfs: fix gfp flags masking in the compression code\n Btrfs: don\u0027t look at bio flags after submit_bio\n btrfs: using btrfs_stack_device_id() get devid\n btrfs: use memparse\n Btrfs: add a \"df\" ioctl for btrfs\n Btrfs: cache the extent state everywhere we possibly can V2\n Btrfs: cache ordered extent when completing io\n Btrfs: cache extent state in find_delalloc_range\n Btrfs: change the ordered tree to use a spinlock instead of a mutex\n Btrfs: finish read pages in the order they are submitted\n btrfs: fix btrfs_mkdir goto for no free objectids\n Btrfs: flush data on snapshot creation\n Btrfs: make df be a little bit more understandable\n ...\n" }, { "commit": "2ac55d41b5d6bf49e76bc85db5431240617e2f8f", "tree": "ee8e2a716ef0b50388ef5e4a86387ec0499bca89", "parents": [ "5a1a3df1f6c86926cfe8657e6f9b4b4c2f467d60" ], "author": { "name": "Josef Bacik", "email": "josef@redhat.com", "time": "Wed Feb 03 19:33:23 2010 +0000" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Mon Mar 15 11:00:13 2010 -0400" }, "message": "Btrfs: cache the extent state everywhere we possibly can V2\n\nThis patch just goes through and fixes everybody that does\n\nlock_extent()\nblah\nunlock_extent()\n\nto use\n\nlock_extent_bits()\nblah\nunlock_extent_cached()\n\nand pass around a extent_state so we only have to do the searches once per\nfunction.

I\nalso changed the clear_extent_bit() to only unset the cached state if we are\nclearing EXTENT_LOCKED and related stuff, so we can do things like this\n\nlock_extent_bits()\nclear delalloc bits\nunlock_extent_cached()\n\nwithout losing our cached state. I tested this thoroughly and turned on\nLEAK_DEBUG to make sure we weren\u0027t leaking extent states, everything worked out\nfine.\n\nSigned-off-by: Josef Bacik \u003cjosef@redhat.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "0813e22d4e0d618eac9b47bec942bf856adca4c5", "tree": "4d2b1a9717e6cdbab7966ce2d0ae698a52d46ae0", "parents": [ "382640b3372405c40b7646c68a50ca91358027e4", "3f6fae9559225741c91f1320090b285da1413290" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Feb 15 19:56:21 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Feb 15 19:56:21 2010 -0800" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable:\n Btrfs: btrfs_mark_extent_written uses the wrong slot\n" }, { "commit": "3f6fae9559225741c91f1320090b285da1413290", "tree": "94c1a90aaed740d80cfa701b8c4abad5bbb699df", "parents": [ "23b5c50945f2294add0137799400329c0ebba290" ], "author": { "name": "Shaohua Li", "email": "shaohua.li@intel.com", "time": "Thu Feb 11 07:43:00 2010 +0000" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Fri Feb 12 16:47:19 2010 -0500" }, "message": "Btrfs: btrfs_mark_extent_written uses the wrong slot\n\nMy test do: fallocate a big file and do write.
