Ext4\n(e9e3bcecf44c04b9e6b505fd8e2eb9cea58fb94d) and xfs recently had to fix\nsimilar issues.\n\nIn our case what happens is that we can have an outstanding aio on a region\nand if a write comes in with some bytes overlapping the original aio we may\ndecide to read that region into a page before continuing (typically because\nof buffered-io fallback).  Since we have no ordering guarantees with the\naio, we can read stale or bad data into the page and then write it back out.\n\nIf the i/o is page and block aligned, then we avoid this issue as there\nwon\u0027t be any need to read data from disk.\n\nI took the same approach as Eric in the ext4 patch and introduced some\nserialization of unaligned async direct i/o.  I don\u0027t expect this to have an\neffect on the most common cases of AIO.  Unaligned aio will be slower\nthough, but that\u0027s far more acceptable than data corruption.\n\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\nSigned-off-by: Joel Becker \u003cjlbec@evilplan.org\u003e\n"

      "message": "ocfs2: Try to free truncate log when meeting ENOSPC in write.\n\nRecently, one of our colleagues meet with a problem that if we\nwrite/delete a 32mb files repeatly, we will get an ENOSPC in\nthe end. And the corresponding bug is 1288.\nhttp://oss.oracle.com/bugzilla/show_bug.cgi?id\u003d1288\n\nThe real problem is that although we have freed the clusters,\nthey are in truncate log and they will be summed up so that\nwe can free them once in a whole.\n\nSo this patch just try to resolve it. In case we see -ENOSPC\nin ocfs2_write_begin_no_lock, we will check whether the truncate\nlog has enough clusters for our need, if yes, we will try to\nflush the truncate log at that point and try again.

      "message": "direct-io: cleanup blockdev_direct_IO locking\n\nCurrently the locking in blockdev_direct_IO is a mess, we have three\ndifferent locking types and very confusing checks for some of them.  The\nmost complicated one is DIO_OWN_LOCKING for reads, which happens to not\nactually be used.\n\nThis patch gets rid of the DIO_OWN_LOCKING - as mentioned above the read\ncase is unused anyway, and the write side is almost identical to\nDIO_NO_LOCKING.  The difference is that DIO_NO_LOCKING always sets the\ncreate argument for the get_blocks callback to zero, but we can easily\nmove that to the actual get_blocks callbacks.  There are four users of the\nDIO_NO_LOCKING mode: gfs already ignores the create argument and thus is\nfine with the new version, ocfs2 only errors out if create were ever set,\nand we can remove this dead code now, the block device code only ever uses\ncreate for an error message if we are fully beyond the device which can\nnever happen, and last but not least XFS will need the new behavour for\nwrites.\n\nNow we can replace the lock_type variable with a flags one, where no flag\nmeans the DIO_NO_LOCKING behaviour and DIO_LOCKING is kept as the first\nflag.  Separate out the check for not allowing to fill holes into a\nseparate flag, although for now both flags always get set at the same\ntime.\n\nAlso revamp the documentation of the locking scheme to actually make\nsense.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nCc: Zach Brown \u003czach.brown@oracle.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Alex Elder \u003caelder@sgi.com\u003e\nCc: Mark Fasheh \u003cmfasheh@suse.com\u003e\nCc: Joel Becker \u003cjoel.becker@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "Pagecache zeroing: zero_user_segment, zero_user_segments and zero_user\n\nSimplify page cache zeroing of segments of pages through 3 functions\n\nzero_user_segments(page, start1, end1, start2, end2)\n\n        Zeros two segments of the page. It takes the position where to\n        start and end the zeroing which avoids length calculations and\n\tmakes code clearer.\n\nzero_user_segment(page, start, end)\n\n        Same for a single segment.\n\nzero_user(page, start, length)\n\n        Length variant for the case where we know the length.\n\nWe remove the zero_user_page macro. Issues:\n\n1. Its a macro. Inline functions are preferable.\n\n2. The KM_USER0 macro is only defined for HIGHMEM.\n\n   Having to treat this special case everywhere makes the\n   code needlessly complex. The parameter for zeroing is always\n   KM_USER0 except in one single case that we open code.\n\nAvoiding KM_USER0 makes a lot of code not having to be dealing\nwith the special casing for HIGHMEM anymore. Dealing with\nkmap is only necessary for HIGHMEM configurations. In those\nconfigurations we use KM_USER0 like we do for a series of other\nfunctions defined in highmem.h.\n\nSince KM_USER0 is depends on HIGHMEM the existing zero_user_page\nfunction could not be a macro. zero_user_* functions introduced\nhere can be be inline because that constant is not used when these\nfunctions are called.\n\nAlso extract the flushing of the caches to be outside of the kmap.\n\n[akpm@linux-foundation.org: fix nfs and ntfs build]\n[akpm@linux-foundation.org: fix ntfs build some more]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Steven French \u003csfrench@us.ibm.com\u003e\nCc: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nCc: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: \"J.

      "message": "mm: merge populate and nopage into fault (fixes nonlinear)\n\nNonlinear mappings are (AFAIKS) simply a virtual memory concept that encodes\nthe virtual address -\u003e file offset differently from linear mappings.\n\n-\u003epopulate is a layering violation because the filesystem/pagecache code\nshould need to know anything about the virtual memory mapping.  The hitch here\nis that the -\u003enopage handler didn\u0027t pass down enough information (ie.  pgoff).\n But it is more logical to pass pgoff rather than have the -\u003enopage function\ncalculate it itself anyway (because that\u0027s a similar layering violation).\n\nHaving the populate handler install the pte itself is likewise a nasty thing\nto be doing.\n\nThis patch introduces a new fault handler that replaces -\u003enopage and\n-\u003epopulate and (later) -\u003enopfn.  Most of the old mechanism is still in place\nso there is a lot of duplication and nice cleanups that can be removed if\neveryone switches over.\n\nThe rationale for doing this in the first place is that nonlinear mappings are\nsubject to the pagefault vs invalidate/truncate race too, and it seemed stupid\nto duplicate the synchronisation logic rather than just consolidate the two.\n\nAfter this patch, MAP_NONBLOCK no longer sets up ptes for pages present in\npagecache.  Seems like a fringe functionality anyway.\n\nNOPAGE_REFAULT is removed.  This should be implemented with -\u003efault, and no\nusers have hit mainline yet.\n\n[akpm@linux-foundation.org: cleanup]\n[randy.dunlap@oracle.com: doc. fixes for readahead]\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nCc: Mark Fasheh \u003cmark.fasheh@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
