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": "5dd4056db84387975140ff2568eaa0406f07985e", "tree": "03c26d7f6e3367b167bfeeb1a01654c6619573f4", "parents": [ "49792c806d0bfd53afc789dcdf50dc9bed2c5b83" ], "author": { "name": "Christoph Hellwig", "email": "hch@infradead.org", "time": "Wed Mar 03 09:05:00 2010 -0500" }, "committer": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Fri Mar 05 00:20:28 2010 +0100" }, "message": "dquot: cleanup space allocation / freeing routines\n\nGet rid of the alloc_space, free_space, reserve_space, claim_space and\nrelease_rsv dquot operations - they are always called from the filesystem\nand if a filesystem really needs their own (which none currently does)\nit can just call into it\u0027s own routine directly.\n\nMove shared logic into the common __dquot_alloc_space,\ndquot_claim_space_nodirty and __dquot_free_space low-level methods,\nand rationalize the wrappers around it to move as much as possible\ncode into the common block for CONFIG_QUOTA vs not.

While\ntrying to fix them, it seems quite confusing in the ext3 code where some\nblocks are filesystem-wide blocks, some are group relative offsets that need\nto be signed value (as -1 has special meaning). So it seem saner to define\ntwo types of physical blocks: one is filesystem wide blocks, another is\ngroup-relative blocks. The following patches clarify these two types of\nblocks in the ext3 code, and fix the type bugs which limit current 32 bit ext3\nfilesystem limit to 8TB.\n\nWith this series of patches and the percpu counter data type changes in the mm\ntree, we are able to extend exts filesystem limit to 16TB.\n\nThis work is also a pre-request for the recent \u003e32 bit ext3 work, and makes\nthe kernel to able to address 48 bit ext3 block a lot easier: Simply redefine\next3_fsblk_t from unsigned long to sector_t and redefine the format string for\next3 filesystem block corresponding.\n\nTwo RFC with a series patches have been posted to ext2-devel list and have\nbeen reviewed and discussed:\nhttp://marc.theaimsgroup.com/?l\u003dext2-devel\u0026m\u003d114722190816690\u0026w\u003d2\n\nhttp://marc.theaimsgroup.com/?l\u003dext2-devel\u0026m\u003d114784919525942\u0026w\u003d2\n\nPatches are tested on both 32 bit machine and 64 bit machine, \u003c8TB ext3 and\n\u003e8TB ext3 filesystem(with the latest to be released e2fsprogs-1.39).

Holding the lock during\nbitmap scan is unnecessary and could possibly cause scalability issue and\nlatency issues.\n\nThis patch tries to address this by dropping the lock before scan the\nbitmap. Before that we need to reserve the open window in case someone\nelse is targetting at the same window. Question was should we reserve the\nwhole free reservable space or just the window size we need. Reserve the\nwhole free reservable space will possibly force other threads which\nintended to do block allocation nearby move to another block group(cause\nbad layout). In this patch, we just reserve the desired size before drop\nthe lock and scan the block bitmap. This patch fixed a ext3 reservation\nlatency issue seen on a cvs check out test. Patch is tested with many fsx,\ntiobench, dbench and untar a kernel test.\n\nSigned-Off-By: Mingming Cao \u003ccmm@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
