      "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"

      "message": "GFS2: free disk inode which is deleted by remote node -V2\n\nthis patch is for the same problem that Benjamin Marzinski fixes at commit\nb94a170e96dc416828af9d350ae2e34b70ae7347\n\nquotation of the original problem:\n\n---cut here---\nWhen a file is deleted from a gfs2 filesystem on one node, a dcache\nentry for it may still exist on other nodes in the cluster. If this\nhappens, gfs2 will be unable to free this file on disk. Because of this,\nit\u0027s possible to have a gfs2 filesystem with no files on it and no free\nspace. With this patch, when a node receives a callback notifying it\nthat the file is being deleted on another node, it schedules a new\nworkqueue thread to remove the file\u0027s dcache entry.\n---end cut---\n\nafter applying Benjamin\u0027s patch, I think there is still a case in which the disk\ninode remains even when \"no space\" is hit. the case is that when running\nd_prune_aliases() against the inode, there are one or more dentries(aliases)\nwhich have reference count number \u003e 0. in this case the dentries won\u0027t be pruned.\nand even later, the reference count becomes to 0, the dentries can still be\ncached in memory. unfortunately, no callback come again, things come back to\nthe state before the callback runs. thus the on disk inode remains there until\nin memoryinode is removed for some other reason(shrinking inode cache or unmount\nthe volume..).\n\nthis patch is to remove those dentries when their reference count becomes to 0 and\nthe inode is deleted by remote node. for implementation, gfs2_dentry_delete() is\nadded as dentry_operations.d_delete. the function returns true when the inode is\ndeleted by remote node. in dput(), gfs2_dentry_delete() is called and since it\nreturns true, the dentry is unhashed from dcache and then removed. when all dentries\nare removed, the in memory inode get removed so that the on disk inode is freed.\n\nSigned-off-by: Wengang Wang \u003cwen.gang.wang@oracle.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n\n"

      "message": "[GFS2] Clean up inode number handling\n\nThis patch cleans up the inode number handling code. The main difference\nis that instead of looking up the inodes using a struct gfs2_inum_host\nwe now use just the no_addr member of this structure. The tests relating\nto no_formal_ino can then be done by the calling code. This has\nadvantages in that we want to do different things in different code\npaths if the no_formal_ino doesn\u0027t match. In the NFS patch we want to\nreturn -ESTALE, but in the -\u003elookup() path, its a bug in the fs if the\nno_formal_ino doesn\u0027t match and thus we can withdraw in this case.\n\nIn order to later fix bz #201012, we need to be able to look up an inode\nwithout knowing no_formal_ino, as the only information that is known to\nus is the on-disk location of the inode in question.\n\nThis patch will also help us to fix bz #236099 at a later date by\ncleaning up a lot of the code in that area.\n\nThere are no user visible changes as a result of this patch and there\nare no changes to the on-disk format either.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

This is now fixed.\n\nAlso some other tidy ups are included:\n\n - We use GFS2\u0027s hash function for dentries (see ops_dentry.c) so that\n   we don\u0027t have to keep recalculating the hash values.\n - A lot of common code is eliminated between the various directory\n   lookup routines.\n - Better error checking on directory lookup (previously different\n   routines checked for different errors)\n - The leaf split operation has a couple of redundant operations\n   removed from it, so it should be faster.\n\nThere is still further scope for further clean ups in the directory\ncode, and readdir in particular could do with slimming down a bit.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"
