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": "5a0e3ad6af8660be21ca98a971cd00f331318c05", "tree": "5bfb7be11a03176a87296a43ac6647975c00a1d1", "parents": [ "ed391f4ebf8f701d3566423ce8f17e614cde9806" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Wed Mar 24 17:04:11 2010 +0900" }, "committer": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Tue Mar 30 22:02:32 2010 +0900" }, "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files. percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed. Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "e213e26ab3988c516c06eba4dcd030ac052f6dc9", "tree": "6e26fbdbb842b387697d73daf6e70cf718269a77", "parents": [ "c812a51d11bbe983f4c24e32b59b265705ddd3c2", "efd8f0e6f6c1faa041f228d7113bd3a9db802d49" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 05 13:20:53 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 05 13:20:53 2010 -0800" }, "message": "Merge branch \u0027for_linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs-2.6\n\n* \u0027for_linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs-2.6: (33 commits)\n quota: stop using QUOTA_OK / NO_QUOTA\n dquot: cleanup dquot initialize routine\n dquot: move dquot initialization responsibility into the filesystem\n dquot: cleanup dquot drop routine\n dquot: move dquot drop responsibility into the filesystem\n dquot: cleanup dquot transfer routine\n dquot: move dquot transfer responsibility into the filesystem\n dquot: cleanup inode allocation / freeing routines\n dquot: cleanup space allocation / freeing routines\n ext3: add writepage sanity checks\n ext3: Truncate allocated blocks if direct IO write fails to update i_size\n quota: Properly invalidate caches even for filesystems with blocksize \u003c pagesize\n quota: generalize quota transfer interface\n quota: sb_quota state flags cleanup\n jbd: Delay discarding buffers in journal_unmap_buffer\n ext3: quota_write cross block boundary behaviour\n quota: drop permission checks from xfs_fs_set_xstate/xfs_fs_set_xquota\n quota: split out compat_sys_quotactl support from quota.c\n quota: split out netlink notification support from quota.c\n quota: remove invalid optimization from quota_sync_all\n ...\n\nFixed trivial conflicts in fs/namei.c and fs/ufs/inode.c\n" }, { "commit": "c7e8d4d6dceeb6fd236991f590d3fa6f97c59874", "tree": "79404097d7e2a94bf642ba427252dd662937f0f9", "parents": [ "e1f5c67a1994312300ebc41195e6f5bea2f6c065" ], "author": { "name": "Christoph Egger", "email": "siccegge@stud.informatik.uni-erlangen.de", "time": "Fri Feb 05 14:13:33 2010 +0100" }, "committer": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Fri Mar 05 00:20:20 2010 +0100" }, "message": "jbd[2]: remove references to BUFFER_DEBUG\n\nCONFIG_BUFFER_DEBUG seems to have been removed from the documentation\nsomewhere around 2.4.15 and seemingly hasn\u0027t been available even\nlonger.

Contrast this with a journal or\ntransaction in which multiple places may want to watch the entire\ntransaction separately.\n\nThe trigger sets are considered static allocation from the jbd2\nperspective. ocfs2 will just have one trigger set per block type,\nsetting the same set on every bh of the same type.\n\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\nCc: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "e97fcd95a4778a8caf1980c6c72fdf68185a0838", "tree": "795c007ed03c091c860df8b03986fbe444f51530", "parents": [ "19ece546a418997226bd91552fbc41abcb05cea6" ], "author": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Tue Nov 18 17:15:24 2008 -0800" }, "committer": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Mon Jan 05 08:40:24 2009 -0800" }, "message": "jbd2: Add BH_JBDPrivateStart\n\nAdd this so that file systems using JBD2 can safely allocate unused b_state\nbits.\n\nIn this case, we add it so that Ocfs2 can define a single bit for tracking\nthe validation state of a buffer.\n\nAcked-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "c31910672376dfb8d020e32afa7249763bcd924a", "tree": "3f2b95a1d4a4da76d85d5bf32534fa3d15a82eac", "parents": [ "c39a7f84d7845aa95d1c7c168f38215aedcc13c2" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Tue Jan 06 11:14:25 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Tue Jan 06 11:14:25 2009 -0500" }, "message": "ext4: Remove code to create the journal inode\n\nThis code has been obsolete in quite some time, since the supported\nmethod for adding a journal inode is to use tune2fs (or to creating\nnew filesystem with a journal via mke2fs or mkfs.ext4).\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "fb68407b0d9efba962c03f55009c797e22f024bc", "tree": "b3f33f513969d6f77c5b6a6f71b662057d3440a5", "parents": [ "c3a326a657562dab81acf05aee106dc1fe345eb4" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Thu Nov 06 17:50:21 2008 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Thu Nov 06 17:50:21 2008 -0500" }, "message": "jbd2: Call journal commit callback without holding j_list_lock\n\nAvoid freeing the transaction in __jbd2_journal_drop_transaction() so\nthe journal commit callback can run without holding j_list_lock, to\navoid lock contention on this spinlock.\n\nSigned-off-by: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "1a0d3786dd57dbd74f340322054c3d618b999dcf", "tree": "b10b3ed6cb60ee34a4e8140e60da2ecc34b52f32", "parents": [ "498e5f24158da7bf8fa48074a70e370e22844492" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Nov 05 00:09:22 2008 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Nov 05 00:09:22 2008 -0500" }, "message": "jbd2: Remove a large array of bh\u0027s from the stack of the checkpoint routine\n\njbd2_log_do_checkpoint()n is one of the kernel\u0027s largest stack users.\nMove the array of buffer head\u0027s from the stack of jbd2_log_do_checkpoint()\nto the in-core journal structure.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "30773840c19cea60dcef39545960d541b1ac1cf8", "tree": "f220a2dce451a40dc7264e8fd70c77c5a3908873", "parents": [ "d7cfa4684d82f58e5d7cb73b8a3c88c169937f25" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sat Jan 03 20:27:38 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sat Jan 03 20:27:38 2009 -0500" }, "message": "ext4: add fsync batch tuning knobs\n\nAdd new mount options, min_batch_time and max_batch_time, which\ncontrols how long the jbd2 layer should wait for additional filesystem\noperations to get batched with a synchronous write transaction.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "e07f7183a486cf9783d1f8c9d2997b5b39eeb2d4", "tree": "74ed3a563add5fa57e80af03f3f712f2910ac39f", "parents": [ "032115fcef837a00336ddf7bda584e89789ea498" ], "author": { "name": "Josef Bacik", "email": "jbacik@redhat.com", "time": "Wed Nov 26 01:14:26 2008 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Nov 26 01:14:26 2008 -0500" }, "message": "jbd2: improve jbd2 fsync batching\n\nThis patch removes the static sleep time in favor of a more self\noptimizing approach where we measure the average amount of time it\ntakes to commit a transaction to disk and the ammount of time a\ntransaction has been running.
