However, if the bh has already been\nwritten and the bh reclaimed for some other purpose, AND if the inode\nis the only one in the inode table block in use, then\next4_get_inode_loc() will not read the inode table block from disk,\nbut as an optimization, fill the block with zero\u0027s assuming that its\ncaller will copy in the on-disk version of the inode.  This is not\ndone by ext4_write_inode(), so the contents of the inode can simply\nget lost.  The fix is to use __ext4_get_inode_loc() with in_mem set to\n0, instead of ext4_get_inode_loc().

      "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"

For most metadata operations\nthis is a straight forward move into the methods, but for truncate and\nopen it\u0027s a bit more complicated.\n\nFor truncate we currently only call vfs_dq_init for the sys_truncate case\nbecause open already takes care of it for ftruncate and open(O_TRUNC) - the\nnew code causes an additional vfs_dq_init for those which is harmless.\n\nFor open the initialization is moved from do_filp_open into the open method,\nwhich means it happens slightly earlier now, and only for regular files.\nThe latter is fine because we don\u0027t need to initialize it for operations\non special files, and we already do it as part of the namespace operations\nfor directories.\n\nAdd a dquot_file_open helper that filesystems that support generic quotas\ncan use to fill in -\u003eopen.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n"

      "message": "ext4: Fix fencepost error in chosing choosing group vs file preallocation.\n\nThe ext4 multiblock allocator decides whether to use group or file\npreallocation based on the file size.  When the file size reaches\ns_mb_stream_request (default is 16 blocks), it changes to use a\nfile-specific preallocation. This is cool, but it has a tiny problem.\n\nSee a simple script:\nmkfs.ext4 -b 1024 /dev/sda8 1000000\nmount -t ext4 -o nodelalloc /dev/sda8 /mnt/ext4\nfor((i\u003d0;i\u003c5;i++))\ndo\ncat /mnt/4096\u003e\u003e/mnt/ext4/a\t#4096 is a file with 4096 characters.\ncat /mnt/4096\u003e\u003e/mnt/ext4/b\ndone\ndebuge4fs -R \u0027stat a\u0027 /dev/sda8|grep BLOCKS -A 1\n\nAnd you get\nBLOCKS:\n(0-14):8705-8719, (15):2356, (16-19):8465-8468\n\nSo there are 3 extents, a bit strange for the lonely 15th logical\nblock.  As we write to the 16 blocks, we choose file preallocation in\next4_mb_group_or_file, but in ext4_mb_normalize_request, we meet with\nthe 16*1024 range, so no preallocation will be carried. file b then\nreserves the space after \u00272356\u0027, so when when write 16, we start from\nanother part.\n\nThis patch just change the check in ext4_mb_group_or_file, so\nthat for the lonely 15 we will still use group preallocation.\nAfter the patch, we will get:\ndebuge4fs -R \u0027stat a\u0027 /dev/sda8|grep BLOCKS -A 1\nBLOCKS:\n(0-15):8705-8720, (16-19):8465-8468\n\nLooks more sane.
