This commit made UBIFS set the \u0027MS_RDONLY\u0027 flag in the\nVFS superblock when it switches to R/O mode due to an error. This was done\nto make VFS show the R/O UBIFS flag in /proc/mounts.\n\nHowever, several places in UBIFS relied on the \u0027MS_RDONLY\u0027 flag and assume this\nflag can only change when we re-mount. For example, \u0027ubifs_put_super()\u0027.\n\nThis patch introduces new UBIFS flag - \u0027c-\u003ero_mount\u0027 which changes only when\nwe re-mount, and preserves the way UBIFS was originally mounted (R/W or R/O).\nThis allows us to de-initialize UBIFS cleanly in \u0027ubifs_put_super()\u0027.\n\nThis patch also changes all \u0027ubifs_assert(!c-\u003ero_media)\u0027 assertions to\n\u0027ubifs_assert(!c-\u003ero_media \u0026\u0026 !c-\u003ero_mount)\u0027, because we never should write\nanything if the FS was mounter R/O.\n\nAll the places where we test for \u0027MS_RDONLY\u0027 flag in the VFS SB were changed\nand now we test the \u0027c-\u003ero_mount\u0027 flag instead, because it preserves the\noriginal UBIFS mount type, unlike the \u0027MS_RDONLY\u0027 flag.\n\nSigned-off-by: Artem Bityutskiy \u003cArtem.Bityutskiy@nokia.com\u003e\n"

      "message": "UBIFS: introduce new flag for RO due to errors\n\nThe R/O state may have various reasons:\n\n1. The UBI volume is R/O\n2. The FS is mounted R/O\n3. The FS switched to R/O mode because of an error\n\nHowever, in UBIFS we have only one variable which represents cases\n1 and 3 - \u0027c-\u003ero_media\u0027. Indeed, we set this to 1 if we switch to\nR/O mode due to an error, and then we test it in many places to\nmake sure that we stop writing as soon as the error happens.\n\nBut this is very unclean. One consequence of this, for example, is\nthat in \u0027ubifs_remount_fs()\u0027 we use \u0027c-\u003ero_media\u0027 to check whether\nwe are in R/O mode because on an error, and we print a message\nin this case. However, if we are in R/O mode because the media\nis R/O, our message is bogus.\n\nThis patch introduces new flag - \u0027c-\u003ero_error\u0027 which is set when\nwe switch to R/O mode because of an error. It also changes all\n\"if (c-\u003ero_media)\" checks to \"if (c-\u003ero_error)\" checks, because\nthis is what the checks actually mean. We do not need to check\nfor \u0027c-\u003ero_media\u0027 because if the UBI volume is in R/O mode, we\ndo not allow R/W mounting, and now writes can happen. This is\nguaranteed by VFS. But it is good to double-check this, so this\npatch also adds many \"ubifs_assert(!c-\u003ero_media)\" checks.\n\nIn the \u0027ubifs_remount_fs()\u0027 function this patch makes a bit more\nchanges - it fixes the error messages as well.\n\nSigned-off-by: Artem Bityutskiy \u003cArtem.Bityutskiy@nokia.com\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"
