      "message": "[GFS2] Clean up the glock core\n\nThis patch implements a number of cleanups to the core of the\nGFS2 glock code. As a result a lot of code is removed. It looks\nlike a really big change, but actually a large part of this patch\nis either removing or moving existing code.\n\nThere are some new bits too though, such as the new run_queue()\nfunction which is considerably streamlined. Highlights of this\npatch include:\n\n o Fixes a cluster coherency bug during SH -\u003e EX lock conversions\n o Removes the \"glmutex\" code in favour of a single bit lock\n o Removes the -\u003ego_xmote_bh() for inodes since it was duplicating\n   -\u003ego_lock()\n o We now only use the -\u003elm_lock() function for both locks and\n   unlocks (i.e. unlock is a lock with target mode LM_ST_UNLOCKED)\n o The fast path is considerably shortly, giving performance gains\n   especially with lock_nolock\n o The glock_workqueue is now used for all the callbacks from the DLM\n   which allows us to simplify the lock_dlm module (see following patch)\n o The way is now open to make further changes such as eliminating the two\n   threads (gfs2_glockd and gfs2_scand) in favour of a more efficient\n   scheme.\n\nThis patch has undergone extensive testing with various test suites\nso it should be pretty stable by now.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\nCc: Bob Peterson \u003crpeterso@redhat.com\u003e\n"

      "message": "[GFS2] delay glock demote for a minimum hold time\n\nWhen a lot of IO, with some distributed mmap IO, is run on a GFS2 filesystem in\na cluster, it will deadlock. The reason is that do_no_page() will repeatedly\ncall gfs2_sharewrite_nopage(), because each node keeps giving up the glock\ntoo early, and is forced to call unmap_mapping_range(). This bumps the\nmapping-\u003etruncate_count sequence count, forcing do_no_page() to retry. This\npatch institutes a minimum glock hold time a tenth a second.  This insures\nthat even in heavy contention cases, the node has enough time to get some\nuseful work done before it gives up the glock.\n\nA second issue is that when gfs2_glock_dq() is called from within a page fault\nto demote a lock, and the associated page needs to be written out, it will\ntry to acqire a lock on it, but it has already been locked at a higher level.\nThis patch puts makes gfs2_glock_dq() use the work queue as well, to avoid this\nissue.

In inode_go_sync(), if you do the\ngfs2_log_flush() before this, after the filemap_fdatawrite() call, the glock\nand its associated data buffers will be on the log again. This means you can\ndemote a lock from exclusive, without having it flushed from the log. The\nattached patch simply moves the gfs2_log_flush up to after the\nfilemap_fdatawrite() call.\n\nOriginally, I tried moving the gfs2_log_flush to after gfs2_meta_sync(), but\nthat caused me to trip the following assert.\n\nGFS2: fsid\u003dcypher-36:test.0: fatal: assertion \"!buffer_busy(bh)\" failed\nGFS2: fsid\u003dcypher-36:test.0:   function \u003d gfs2_ail_empty_gl, file \u003d fs/gfs2/glops.c, line \u003d 61\n\nIt appears that gfs2_log_flush() puts some of the glocks buffers in the busy\nstate and the filemap_fdatawrite() call is necessary to flush them.

Presumably these includes were once needed for\nmacros that used to live in sched.h, but moved to other header files in the\ncourse of cleaning it up.\n\nTo ease the pain, this time I did not fiddle with any header files and only\nremoved #includes from .c-files, which tend to cause less trouble.\n\nCompile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,\narm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,\nallmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all\nconfigs in arch/arm/configs on arm.

Also incore.h has been updated to remove forward structure\ndeclarations which are not required.\n\nThe gfs2_quota_lvb structure has now had endianess annotations added\nto it. Also quota.c has been updated so that we now store the\nlvb data locally in endian independant format to avoid needing\na structure in host endianess too. As a result the endianess\nconversions are done as required at various points and thus the\nconversion routines in lvb.[ch] are no longer required.

      "message": "[GFS2] Fix unlinked file handling\n\nThis patch fixes the way we have been dealing with unlinked,\nbut still open files. It removes all limits (other than memory\nfor inodes, as per every other filesystem) on numbers of these\nwhich we can support on GFS2. It also means that (like other\nfs) its the responsibility of the last process to close the file\nto deallocate the storage, rather than the person who did the\nunlinking. Note that with GFS2, those two events might take place\non different nodes.\n\nAlso there are a number of other changes:\n\n o We use the Linux inode subsystem as it was intended to be\nused, wrt allocating GFS2 inodes\n o The Linux inode cache is now the point which we use for\nlocal enforcement of only holding one copy of the inode in\ncore at once (previous to this we used the glock layer).\n o We no longer use the unlinked \"special\" file. We just ignore it\ncompletely. This makes unlinking more efficient.\n o We now use the 4th block allocation state. The previously unused\nstate is used to track unlinked but still open inodes.\n o gfs2_inoded is no longer needed\n o Several fields are now no longer needed (and removed) from the in\ncore struct gfs2_inode\n o Several fields are no longer needed (and removed) from the in core\nsuperblock\n\nThere are a number of future possible optimisations and clean ups\nwhich have been made possible by this patch.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"
