Multiple functions were rewritten to\nremove the need to call gfs2_log_lock(). Instead of using one test to see if\ngfs2_logd had work to do, there are now seperate tests to check if there\nare two many buffers in the incore log or if there are two many items on the\nactive items list.\n\nThis patch is a port of a patch Steve Whitehouse wrote about a year ago, with\nsome minor changes. Since gfs2_ail1_start always submits all the active items,\nit no longer needs to keep track of the first ai submitted, so this has been\nremoved. In gfs2_log_reserve(), the order of the calls to\nprepare_to_wait_exclusive() and wake_up() when firing off the logd thread has\nbeen switched. If it called wake_up first there was a small window for a race,\nwhere logd could run and return before gfs2_log_reserve was ready to get woken\nup. If gfs2_logd ran, but did not free up enough blocks, gfs2_log_reserve()\nwould be left waiting for gfs2_logd to eventualy run because it timed out.\nFinally, gt_logd_secs, which controls how long to wait before gfs2_logd times\nout, and flushes the log, can now be set on mount with ar_commit.\n\nSigned-off-by: Benjamin Marzinski \u003cbmarzins@redhat.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n\n" }, { "commit": "fbd9b09a177a481eda256447c881f014f29034fe", "tree": "ef7e213045382f82a1e3e3cf134d196a1045dd7a", "parents": [ "6b4517a7913a09d3259bb1d21c9cb300f12294bd" ], "author": { "name": "Dmitry Monakhov", "email": "dmonakhov@openvz.org", "time": "Wed Apr 28 17:55:06 2010 +0400" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Wed Apr 28 19:47:36 2010 +0200" }, "message": "blkdev: generalize flags for blkdev_issue_fn functions\n\nThe patch just convert all blkdev_issue_xxx function to common\nset of flags.

First, there were a couple of livelocks where\neverything would come to a halt waiting for a glock that was\nseemingly held by a process that no longer existed. In fact, the\nprocess did exist, it just had the wrong pid number in the holder\ninformation. Second, there was a lock ordering problem between\ninode locking and glock locking. Third, glock/inode contention\ncould sometimes cause inodes to be improperly marked invalid by\niget_failed.\n\nSigned-off-by: Bob Peterson \u003crpeterso@redhat.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": "602c89d2e3e8652f94a697c9a919be739b9bcdd5", "tree": "791c0f4ea2b1f9028f7fdf60dbedd42fa0f8ce06", "parents": [ "4cb947b59c5835783fb96aad2f7d92b1e4250aff" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu Mar 25 14:32:43 2010 +0000" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Mar 29 14:29:17 2010 +0100" }, "message": "GFS2: Clean up stuffed file copying\n\nIf the inode size was corrupt for stuffed files, it was possible\nfor the copying of data to overrun the block and/or page.

This means that the memory usage was rather inefficient.\n\nThe reason for keeping each inode\u0027s metadata in a separate address\nspace is that when glocks are requested on remote nodes, we need to\nbe able to efficiently locate the data and metadata which relating\nto that glock (inode) in order to sync or sync and invalidate it\n(depending on the remotely requested lock mode).\n\nThis patch adds a new type of glock, which has in addition to\nits normal fields, has an address space.
