After packing the\npage got cleared with clear_page_dirty. It did not take into account that\nthe page may be mmaped into other process\u0027s address space. Recent\nreplacement for clear_page_dirty cancel_dirty_page found the confusion with\nsanity check that page has to be not mapped.\n\nThe patch fixes the confusion by making reiserfs avoid tail packing if an\ninode was ever mmapped. reiserfs_mmap and reiserfs_file_release are\nserialized with mutex in reiserfs specific inode. reiserfs_mmap locks the\nmutex and sets a bit in reiserfs specific inode flags.\nreiserfs_file_release checks the bit having the mutex locked. If bit is\nset - tail packing is avoided. This eliminates a possibility that mmapped\npage gets cancel_page_dirty-ed.\n\nSigned-off-by: Vladimir Saveliev \u003cvs@namesys.com\u003e\nCc: Jeff Mahoney \u003cjeffm@suse.com\u003e\nCc: Chris Mason \u003cmason@suse.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "cda9205da24aeaa8fb086b0fb85cdf39571ecc3f", "tree": "c302c3d0b0558d3fc5ac0b5750e4f8150517ece5", "parents": [ "15c945c3d0913d73a7d57d7a0a3c4e2902598cc6" ], "author": { "name": "Chen, Kenneth W", "email": "kenneth.w.chen@intel.com", "time": "Mon Jan 22 20:40:43 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Jan 23 07:52:06 2007 -0800" }, "message": "[PATCH] fix blk_direct_IO bio preparation\n\nFor large size DIO that needs multiple bio, one full page worth of data was\nlost at the boundary of bio\u0027s maximum sector or segment limits.

It does this for sync ops, of course, and for\npartial dio writes that must fall back to buffered and for aio ops that saw\nerrors during submission.\n\nThis means that operations that end up waiting, even if they were issued as\naio ops, will not call aio_complete() from dio.

It was used by the\nsync path to decide when to wake up and finish completing bios and was ignored\nby the async path.\n\nThis patch collapses the two notions into one notion of a dio reference count.\n bios hold a dio reference when they\u0027re between submit_bio and bio-\u003eend_io.\n\nSince bios_in_flight was only used in the sync path it is now equivalent to\ndio-\u003erefcount - 1 which accounts for direct_io_worker() holding a reference\nfor the duration of the operation.\n\ndio_bio_complete() -\u003e finished_one_bio() was called from the sync path after\nfinding bios on the list that the bio-\u003eend_io function had deposited.\nfinished_one_bio() can not drop the dio reference on behalf of these bios now\nbecause bio-\u003eend_io already has. The is_async test in finished_one_bio()\nmeant that it never actually did anything other than drop the bio_count for\nsync callers. So we remove its refcount decrement, don\u0027t call it from\ndio_bio_complete(), and hoist its call up into the async dio_bio_complete()\ncaller after an explicit refcount decrement.

In the worst examples it has\nfailed to call aio_complete() at all (hang) or called it too many times\n(oops).\n\nThis set of patches cleans up the completion phase with the goal of removing\nthe complexity that lead to these bugs. We end up with one path that\ncalculates the result of the operation after all off the bios have completed.\nWe decide when to generate a result of the operation using that path based on\nthe final release of a refcount on the dio structure.\n\nI tried to progress towards the final state in steps that were relatively easy\nto understand. Each step should compile but I only tested the final result of\nhaving all the patches applied.\n\nI\u0027ve tested these on low end PC drives with aio-stress, the direct IO tests I\ncould manage to get running in LTP, orasim, and some home-brew functional\ntests.\n\nIn http://lkml.org/lkml/2006/9/21/103 IBM reports success with ext2 and ext3\nrunning DIO LTP tests. They found that XFS bug which has since been addressed\nin the patch series.\n\nThis patch:\n\nThe mechanics which decide the result of a direct IO operation were duplicated\nin the sync and async paths.\n\nThe async path didn\u0027t check page_errors which can manifest as silently\nreturning success when the final pointer in an operation faults and its\nmatching file region is filled with zeros.\n\nThe sync path and async path differed in whether they passed errors to the\ncaller\u0027s dio-\u003eend_io operation. The async path was passing errors to it which\ntrips an assertion in XFS, though it is apparently harmless.\n\nThis centralizes the completion phase of dio ops in one place. AIO will now\nreturn EFAULT consistently and all paths fall back to the previously sync\nbehaviour of passing the number of bytes \u0027transferred\u0027 to the dio-\u003eend_io\ncallback, regardless of errors.\n\ndio_await_completion() doesn\u0027t have to propogate EIO from non-uptodate bios\nnow that it\u0027s being propogated through dio_complete() via dio-\u003eio_error.
