Furthermore, although theoretically it could trigger under\n normal direct I/O writes, it only seems to trigger if you are issuing\n a huge number of AIO writes, such that a just-written page can get\n evicted from memory, and then read back into memory, before the\n workqueue has a chance to update the extent tree.\n\n This race has been around for a little over a year, and no one noticed\n until two months ago; it only happens under fairly exotic conditions,\n and in fact even after trying very hard to create a simple repro under\n lab conditions, we could only reproduce the problem and confirm the\n fix on production servers running MySQL on very fast PCIe-attached\n flash devices.\n\n Given that Dave was able to hit this problem pretty quickly, if we\n confirm that this commit is at fault, the only reasonable thing to do\n is to revert it IMO.\"\n\nReported-and-tested-by: Dave Jones \u003cdavej@redhat.com\u003e\nAcked-by: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "71db34fc4330f7c784397acb9f1e6ee7f7b32eb2", "tree": "77dd08f6f778a799dcd0c48eb72d0742349df235", "parents": [ "50483c3268918ee51a56d1baa39b9149d2d0d521", "797a9d797f8483bb67f265c761b76dcd5a077a23" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 29 14:53:25 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 29 14:53:25 2012 -0700" }, "message": "Merge branch \u0027for-3.4\u0027 of git://linux-nfs.org/~bfields/linux\n\nPull nfsd changes from Bruce Fields:\n\nHighlights:\n - Benny Halevy and Tigran Mkrtchyan implemented some more 4.1 features,\n moving us closer to a complete 4.1 implementation.\n - Bernd Schubert fixed a long-standing problem with readdir cookies on\n ext2/3/4.\n - Jeff Layton performed a long-overdue overhaul of the server reboot\n recovery code which will allow us to deprecate the current code (a\n rather unusual user of the vfs), and give us some needed flexibility\n for further improvements.\n - Like the client, we now support numeric uid\u0027s and gid\u0027s in the\n auth_sys case, allowing easier upgrades from NFSv2/v3 to v4.x.\n\nPlus miscellaneous bugfixes and cleanup.\n\nThanks to everyone!\n\nThere are also some delegation fixes waiting on vfs review that I\nsuppose will have to wait for 3.5.

There are several reasons for changing this.\n\nFirstly it is quite non obvious that punching hole needs to\next4_ext_map_blocks() to punch a hole, especially given that this\nfunction should map blocks, not unmap it. It also required a lot of new\ncode in ext4_ext_map_blocks().\n\nSecondly the design of it is not very effective. The reason is that we\nare trying to punch out blocks in ext4_ext_punch_hole() in opposite\ndirection than in ext4_ext_rm_leaf() which causes the ext4_ext_rm_leaf()\nto iterate through the whole tree from the end to the start to find the\nrequested extent for every extent we are going to punch out.\n\nAnd finally the current implementation does not use the existing code,\nbut bring a lot of new code, which is IMO unnecessary since there\nalready is some infrastructure we can use. Specifically\next4_ext_remove_space().\n\nThis commit changes ext4_ext_remove_space() to accept \u0027end\u0027 parameter so\nwe can not only truncate to the end of file, but also remove the space\nin the middle of the file (punch a hole). Moreover, because the last\nblock to punch out, might be in the middle of the extent, we have to\nsplit the extent at \u0027end + 1\u0027 so ext4_ext_rm_leaf() can easily either\nremove the whole fist part of split extent, or change its size.\n\next4_ext_remove_space() is then used to actually remove the space\n(extents) from within the hole, instead of ext4_ext_map_blocks().\n\nNote that this also fix the issue with punch hole, where we would forget\nto remove empty index blocks from the extent tree, resulting in double\nfree block error and file system corruption. This is simply because we\nnow use different code path, where this problem does not exist.\n\nThis has been tested with fsx running for several days and xfstests,\nplus xfstest #251 with \u0027-o discard\u0027 run on the loop image (which\nconverts discard requestes into punch hole to the backing file).

The files are NOT\npreallocated, so you will get writes to random offsets within the\nfile, thus creating holes and extending i_size. It also opens the\nfile with O_DIRECT and O_SYNC.\n\nOn to the problem. When an I/O requires unwritten extent conversion,\nit is queued onto the completed_io_list for the ext4 inode. Two code\npaths will pull work items from this list. The first is the\next4_end_io_work routine, and the second is ext4_flush_completed_IO,\nwhich is called via the fsync path (and O_SYNC handling, as well).\nThere are two issues I\u0027ve found in these code paths. First, if the\nfsync path beats the work routine to a particular I/O, the work\nroutine will free the io_end structure! It does not take into account\nthe fact that the io_end may still be in use by the fsync path. I\u0027ve\nfixed this issue by adding yet another IO_END flag, indicating that\nthe io_end is being processed by the fsync path.\n\nThe second problem is that the work routine will make an assignment to\nio-\u003eflag outside of the lock. I have witnessed this result in a hang\nat umount. Moving the flag setting inside the lock resolved that\nproblem.\n\nThe problem was introduced by commit b82e384c7b (\"ext4: optimize\nlocking for end_io extent conversion\"), which first appeared in 3.2.\nAs such, the fix should be backported to that release (probably along\nwith the unwritten extent conversion race fix).\n\nSigned-off-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nCC: stable@kernel.org\n\n" }, { "commit": "93ef8541d5c3ad1a73057ff358a49d0ee7146d6f", "tree": "70c2a7cac370084edac29ee0156f52d488ee32ab", "parents": [ "f70486055ee351158bd6999f3965ad378b52c694" ], "author": { "name": "Jeff Moyer", "email": "jmoyer@redhat.com", "time": "Mon Mar 05 10:19:52 2012 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Mar 05 10:19:52 2012 -0500" }, "message": "ext4: clean up the flags passed to __blockdev_direct_IO\n\nFor extent-based files, you can perform DIO to holes, as mentioned in\nthe comments in ext4_ext_direct_IO.
