The current failure message in ext2 prints:\n\n  EXT2-fs (loop1): error: blocksize is too small\n\nwhich is not correct in all cases.  This can be demonstrated\nby creating a filesystem with\n\n  # mkfs.ext2 -b 8192\n\non a 4k page system, and attempting to mount it.\n\nChange the error message to a more generic:\n\n  EXT2-fs (loop1): bad blocksize 8192\n\nto match the error message in ext3.\n\nSigned-off-by: Robin Dong \u003csanbai@taobao.com\u003e\nReviewed-by: Coly Li \u003cbosong.ly@taobao.com\u003e\nReviewed-by: Eric Sandeen \u003csandeen@redhat.com\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n"

Thus changing\ni_nlink in a non-atomic manner (which happens in ext2_rename()) can corrupt\nit as reported and analyzed by Josh.\n\nIn fact, there is no good reason to mess with i_nlink of the moved file.\nWe did it presumably to simulate linking into the new directory and unlinking\nfrom an old one. But the practical effect of this is disputable because fsck\ncan possibly treat file as being properly linked into both directories without\nwriting any error which is confusing. So we just stop increment-decrement\ngames with i_nlink which also fixes the corruption.\n\nCC: stable@kernel.org\nCC: Al Viro \u003cviro@ZenIV.linux.org.uk\u003e\nSigned-off-by: Josh Hunt \u003cjohunt@akamai.com\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n"

This is not the (supposed) full path,\njust the last component of the path.\n\nThis is very useful because creating /etc/shadow is different than creating\n/etc/passwd but the kernel hooks are unable to differentiate these\noperations.  We currently require that userspace realize it is doing some\ndifficult operation like that and than userspace jumps through SELinux hoops\nto get things set up correctly.  This patch does not implement new\nbehavior, that is obviously contained in a seperate SELinux patch, but it\ndoes pass the needed name down to the correct LSM hook.

      "message": "fs: icache RCU free inodes\n\nRCU free the struct inode. This will allow:\n\n- Subsequent store-free path walking patch. The inode must be consulted for\n  permissions when walking, so an RCU inode reference is a must.\n- sb_inode_list_lock to be moved inside i_lock because sb list walkers who want\n  to take i_lock no longer need to take sb_inode_list_lock to walk the list in\n  the first place. This will simplify and optimize locking.\n- Could remove some nested trylock loops in dcache code\n- Could potentially simplify things a bit in VM land. Do not need to take the\n  page lock to follow page-\u003emapping.\n\nThe downsides of this is the performance cost of using RCU. In a simple\ncreat/unlink microbenchmark, performance drops by about 10% due to inability to\nreuse cache-hot slab objects. As iterations increase and RCU freeing starts\nkicking over, this increases to about 20%.\n\nIn cases where inode lifetimes are longer (ie. many inodes may be allocated\nduring the average life span of a single inode), a lot of this cache reuse is\nnot applicable, so the regression caused by this patch is smaller.\n\nThe cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU,\nhowever this adds some complexity to list walking and store-free path walking,\nso I prefer to implement this at a later date, if it is shown to be a win in\nreal situations. I haven\u0027t found a regression in any non-micro benchmark so I\ndoubt it will be a problem.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n"

Both later functions are actually the filesystems\nfollow_link inode operation. vfs_kern_mount() is calling the specified\nget_sb function and lets the filesystem do its job by calling the given\nfill_super function.\n\nTherefore I think it is safe to push down the BKL from the VFS to the\nlow-level filesystems get_sb/fill_super operation.\n\n[arnd: do not add the BKL to those file systems that already\n       don\u0027t use it elsewhere]\n\nSigned-off-by: Jan Blunck \u003cjblunck@infradead.org\u003e\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nCc: Matthew Wilcox \u003cmatthew@wil.cx\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\n"

      "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"

However, in ext[234]_lookup(), this\n-ESTALE can be propagated to userspace if the filesystem is corrupted such\nthat a directory entry references a deleted inode.  This leads to a\nmisleading error message - \"Stale NFS file handle\" - and confusion on the\npart of the admin.\n\nThe bug can be easily reproduced by creating a new filesystem, making a\nlink to an unused inode using debugfs, then mounting and attempting to ls\n-l said link.\n\nThis patch thus changes ext2_lookup to return -EIO if it receives -ESTALE\nfrom ext2_iget(), as ext2 does for other filesystem metadata corruption;\nand also invokes the appropriate ext*_error functions when this case is\ndetected.\n\nSigned-off-by: Bryan Donlan \u003cbdonlan@gmail.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
