When the committing of log commit records\noccur, we can get insertions occurring at an LSN that is not at the\nend of the AIL. If there are thousands of items in the AIL on the\ntail LSN, each insertion has to walk the AIL to find the correct\nplace to insert the new item into the AIL. This can consume large\namounts of CPU time and block other operations from occurring while\nthe traversals are in progress.\n\nTo avoid this repeated walk, use a AIL cursor to record\nwhere we should be inserting the new items into the AIL without\nhaving to repeat the walk. The cursor infrastructure already\nprovides this functionality for push walks, so is a simple extension\nof existing code. While this will not avoid the initial walk, it\nwill avoid repeating it tens of thousands of times during a single\ncheckpoint commit.\n\nThis version includes logic improvements from Christoph Hellwig.\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Alex Elder \u003caelder@sgi.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "eedc6389bb43769e82f2779dabd45865d2b892e4", "tree": "539ec1d94607ae7f1d722181df83105e64e3e811", "parents": [ "f24d5457bd706667951021530dd0590a1f3e9464" ], "author": { "name": "Christoph Hellwig", "email": "hch@infradead.org", "time": "Tue Oct 18 10:23:15 2011 -0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Tue Oct 25 07:10:15 2011 +0200" }, "message": "xfs: start periodic workers later\n\ncommit 2bcf6e970f5a88fa05dced5eeb0326e13d93c4a1 upstream\n\nStart the periodic sync workers only after we have finished xfs_mountfs\nand thus fully set up the filesystem structures.

But some of these flags such as O_DIRECT are\narch dependent. So if we have the 9p client and server running on\ndifferent architectures, we end up with client sending client\narchitecture value of these open flag and server will try to map these\nvalues to what its architecture states. For ex: O_DIRECT on a x86 client\nmaps to\n\n#define O_DIRECT 00040000\n\nWhere as on sparc server it will maps to\n\n#define O_DIRECT 0x100000\n\nHence we need to map these open flags to OS/arch independent flag\nvalues.

During page fault,\nshrink_icache_memory is called that in turn evicts another inode\nB. Inode B has some pending io_end work so it calls ext4_ioend_wait()\nthat waits for inode B\u0027s i_ioend_count to become zero. However, inode\nB\u0027s ioend work was queued behind some of inode A\u0027s ioend work on the\nsame cpu\u0027s ext4-dio-unwritten workqueue. As the ext4-dio-unwritten\nthread on that cpu is processing inode A\u0027s ioend work, it tries to\ngrab inode A\u0027s i_mutex lock. Since the i_mutex lock of inode A is\nstill hold before the page fault happened, we enter a deadlock.\n\nAlso moves ext4_flush_completed_IO and ext4_ioend_wait from\next4_destroy_inode() to ext4_evict_inode(). During inode deleteion,\next4_evict_inode() is called before ext4_destroy_inode() and in\next4_evict_inode(), we may call ext4_truncate() without holding\ni_mutex lock. As a result, there is a race between flush_completed_IO\nthat is called from ext4_ext_truncate() and ext4_end_io_work, which\nmay cause corruption on an io_end structure. This change moves\next4_flush_completed_IO and ext4_ioend_wait from ext4_destroy_inode()\nto ext4_evict_inode() to resolve the race between ext4_truncate() and\next4_end_io_work during inode deletion.\n\nSigned-off-by: Jiaying Zhang \u003cjiayingz@google.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "2fb522e963f57a6c0206f67a355b8131b16ef607", "tree": "e8f00987f7956949e4dec58ce2021539381eb1c4", "parents": [ "f5dce23cc163abd3a4ebece8ae9f140426bf8253" ], "author": { "name": "Curt Wohlgemuth", "email": "curtw@google.com", "time": "Sat Aug 13 11:25:18 2011 -0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Aug 29 13:29:10 2011 -0700" }, "message": "ext4: Fix ext4_should_writeback_data() for no-journal mode\n\ncommit 441c850857148935babe000fc2ba1455fe54a6a9 upstream.\n\next4_should_writeback_data() had an incorrect sequence of\ntests to determine if it should return 0 or 1: in\nparticular, even in no-journal mode, 0 was being returned\nfor a non-regular-file inode.\n\nThis meant that, in non-journal mode, we would use\next4_journalled_aops for directories, symlinks, and other\nnon-regular files.

This patch has been a real team effort and has\nreceived a lot of testing.\n\nThe first issue is that the ail lock needs to be held over a few\nmore operations. The lock thats added into gfs2_releasepage() may\npossibly be a candidate for replacing with RCU at some future\npoint, but at this stage we\u0027ve gone for the obvious fix.\n\nThe second issue is that gfs2_write_inode() can end up calling\na glock recursively when called from gfs2_evict_inode() via the\nsyncing code, so it needs a guard added.\n\nThe third issue is that we either need to not truncate the metadata\npages of inodes which have zero link count, but which we cannot\ndeallocate due to them still being in use by other nodes, or we need\nto ensure that those pages have all made it through the journal and\nail lists first. This patch takes the former approach, but the\nlatter has also been tested and there is nothing to choose between\nthem performance-wise. So again, we could revise that decision\nin the future.\n\nAlso, the inode eviction process is now better documented.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\nTested-by: Bob Peterson \u003crpeterso@redhat.com\u003e\nTested-by: Abhijith Das \u003cadas@redhat.com\u003e\nReported-by: Barry J.
