It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.

When a buffer has b_frozen_data, checksum is computed\nfor it instead of b_data but this can result in an old checksum being\nwritten to the filesystem in the following scenario:\n\n1) transaction1 is opened\n2) handle1 is opened\n3) journal_access(handle1, bh)\n - This sets jh-\u003eb_transaction to transaction1\n4) modify(bh)\n5) journal_dirty(handle1, bh)\n6) handle1 is closed\n7) start committing transaction1, opening transaction2\n8) handle2 is opened\n9) journal_access(handle2, bh)\n - This copies off b_frozen_data to make it safe for transaction1 to commit.\n jh-\u003eb_next_transaction is set to transaction2.\n10) jbd2_journal_write_metadata() checksums b_frozen_data\n11) the journal correctly writes b_frozen_data to the disk journal\n12) handle2 is closed\n - There was no dirty call for the bh on handle2, so it is never queued for\n any more journal operation\n13) Checkpointing finally happens, and it just spools the bh via normal buffer\nwriteback. This will write b_data, which was never triggered on and thus\ncontains a wrong (old) checksum.\n\nThis patch fixes the problem by calling the trigger at the moment data is\nfrozen for journal commit - i.e., either when b_frozen_data is created by\ndo_get_write_access or just before we write a buffer to the log if\nb_frozen_data does not exist. We also rename the trigger to t_frozen as\nthat better describes when it is called.\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "5a0790c2c4a18435759a70e1562450035d778339", "tree": "80acb12d0e37196cf60ae4ca150c6b556115f302", "parents": [ "07a038245b28df9196ffb2e8cc626e9b956a4e23" ], "author": { "name": "Andi Kleen", "email": "andi@firstfloor.org", "time": "Mon Jun 14 13:28:03 2010 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Jun 14 13:28:03 2010 -0400" }, "message": "ext4: remove initialized but not read variables\n\nNo real bugs found, just removed some dead code.\n\nFound by gcc 4.6\u0027s new warnings.\n\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "8ac97b74bca1fc8a63b28cc6121519d1cfa2af99", "tree": "04f00eada6c77edd95b6a56446e4a330266274e5", "parents": [ "c2d45b4da042720ae94648b417d0e051742441d4" ], "author": { "name": "Bill Pemberton", "email": "wfp5p@virginia.edu", "time": "Fri Apr 30 09:34:31 2010 -0400" }, "committer": { "name": "Jiri Kosina", "email": "jkosina@suse.cz", "time": "Tue May 11 10:04:36 2010 +0200" }, "message": "jbd2: use NULL instead of 0 when pointer is needed\n\nFixes sparse warning:\n\nfs/jbd2/journal.c:1892:9: warning: Using plain integer as NULL pointer\n\nSigned-off-by: Bill Pemberton \u003cwfp5p@virginia.edu\u003e\nCC: linux-ext4@vger.kernel.org\nSigned-off-by: Jiri Kosina \u003cjkosina@suse.cz\u003e\n" }, { "commit": "d2eecb03936878ec574ade5532fa83df7d75dde7", "tree": "f7ef8bd29096ba6c073308cd3b674857be1545d4", "parents": [ "f8ec9d6837241865cf99bed97bb99f4399fd5a03" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Dec 07 10:36:20 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Dec 07 10:36:20 2009 -0500" }, "message": "ext4: Use slab allocator for sub-page sized allocations\n\nNow that the SLUB seems to be fixed so that it respects the requested\nalignment, use kmem_cache_alloc() to allocator if the block size of\nthe buffer heads to be allocated is less than the page size.\nPreviously, we were using 16k page on a Power system for each buffer,\neven when the file system was using 1k or 4k block size.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n\n" }, { "commit": "3ebfdf885acedafcadceb4007e77438479094135", "tree": "1bd9a4b223aa22e201af9a87868a33ec53605daf", "parents": [ "c8afb44682fcef6273e8b8eb19fab13ddd05b386" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Wed Dec 23 08:05:15 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Dec 23 08:05:15 2009 -0500" }, "message": "jbd2: don\u0027t use __GFP_NOFAIL in journal_init_common()\n\nIt triggers the warning in get_page_from_freelist(), and it isn\u0027t\nappropriate to use __GFP_NOFAIL here anyway.\n\nAddresses http://bugzilla.kernel.org/show_bug.cgi?id\u003d14843\n\nReported-by: Christian Casteyde \u003ccasteyde.christian@free.fr\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "765f8361902d015c864d5e62019b2f139452d7ef", "tree": "f872385ae91fc926b036038e583a7f72ab5f3459", "parents": [ "39bc680a8160bb9d6743f7873b535d553ff61058" ], "author": { "name": "Yin Kangkai", "email": "kangkai.yin@intel.com", "time": "Tue Dec 15 14:48:25 2009 -0800" }, "committer": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Wed Dec 23 13:44:13 2009 +0100" }, "message": "jbd: jbd-debug and jbd2-debug should be writable\n\njbd-debug and jbd2-debug is currently read-only (S_IRUGO), which is not\ncorrect.

Just before writing a metadata\nbuffer to the journal, jbd2 will optionally call a commit trigger associated\nwith the buffer. If the journal is aborted, an abort trigger will be\ncalled on any dirty buffers as they are dropped from pending\ntransactions.\n\nocfs2 will use this feature.\n\nInitially I tried to come up with a more generic trigger that could be\nused for non-buffer-related events like transaction completion. It\ndoesn\u0027t tie nicely, because the information a buffer trigger needs\n(specific to a journal_head) isn\u0027t the same as what a transaction\ntrigger needs (specific to a tranaction_t or perhaps journal_t). So I\nimplemented a buffer set, with the understanding that\njournal/transaction wide triggers should be implemented separately.\n\nThere is only one trigger set allowed per buffer. I can\u0027t think of any\nreason to attach more than one set.
