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 patch allocates the i_alloc\nstructure whenever its needed, and frees it afterward. This decreases\nthe amount of low memory we use at the expense of requiring a memory\nallocation for each page or partial page that we write. A quick test\nwith postmark shows that the overhead is not measurable and I also note\nthat OCFS2 use the same approach.\n\nIn the future I\u0027d like to solve the problem by shrinking down the size\nof the members of the i_alloc structure, but for now, this reduces the\nimmediate problem of using too much low-memory on x86 and doesn\u0027t add\ntoo much overhead.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "b0d5fd307463405fe1f57494fbb37f810715ed6d", "tree": "2a627d7362a6db7eea4c388b0e0f0ceed8362fb5", "parents": [ "398bbe68321947f6763fbc259a01eb548ce19408" ], "author": { "name": "Bob Peterson", "email": "rpeterso@redhat.com", "time": "Tue Dec 11 19:16:09 2007 -0600" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Fri Jan 25 08:14:13 2008 +0000" }, "message": "[GFS2] Only fetch the dinode once in block_map\n\nFunction gfs2_block_map was often looking up the disk inode twice.\nThis optimizes it so that only does it once.\n\nSigned-off-by: Bob Peterson \u003crpeterso@redhat.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "e9e1ef2b6ee401d7c1e1eb38052857b4b206d172", "tree": "68dff93cf4058eb06b162d800f08ff7752cd1a55", "parents": [ "2066b58b0a038d7aedd24133677efb8856cac3a1" ], "author": { "name": "Bob Peterson", "email": "rpeterso@redhat.com", "time": "Mon Dec 10 14:13:27 2007 -0600" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Fri Jan 25 08:08:25 2008 +0000" }, "message": "[GFS2] Remove function gfs2_get_block\n\nThis patch is just a cleanup.

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" }, { "commit": "3a8a9a1034813aa99f5ae3150f652d490c5ff10d", "tree": "427d4c1499b5c88dbf43c6e490d83cee350083b2", "parents": [ "bd8968010a9a08e67a0ddb3ddee9feb8882e8c2f" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 18 15:09:15 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 18 15:09:15 2006 -0400" }, "message": "[GFS2] Update copyright date to 2006\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "bd8968010a9a08e67a0ddb3ddee9feb8882e8c2f", "tree": "c3960853310112779e2ce583a8c8b524777cb70d", "parents": [ "1b50259bc33f2adfcb4c5fba4b740bf80789df22" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 18 14:54:58 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 18 14:54:58 2006 -0400" }, "message": "[GFS2] Remove semaphore.h from C files\n\nWe no longer use semaphores, everything has been converted to\nmutex or rwsem, so we don\u0027t need to include this header any more.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "e90c01e148b967d30caf59e76accb3a58ca6b74b", "tree": "92f9b45febbdbc52174307e2e73dbb26aa893465", "parents": [ "7d63b54a65ce902f9aaa8efe8192aa3b983264d4" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Fri May 12 12:09:15 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Fri May 12 12:09:15 2006 -0400" }, "message": "[GFS2] Reverse block order in build_height\n\nThe original code ordered the blocks allocated in the build_height\nroutine backwards causing excessive disk seeks during a read of the\nmetadata.

There is a lock mode inversion problem related to the resource\n group hold function which needs to be resolved.\n 2.
