      "message": "md: implment REQ_FLUSH/FUA support\n\nThis patch converts md to support REQ_FLUSH/FUA instead of now\ndeprecated REQ_HARDBARRIER.  In the core part (md.c), the following\nchanges are notable.\n\n* Unlike REQ_HARDBARRIER, REQ_FLUSH/FUA don\u0027t interfere with\n  processing of other requests and thus there is no reason to mark the\n  queue congested while FLUSH/FUA is in progress.\n\n* REQ_FLUSH/FUA failures are final and its users don\u0027t need retry\n  logic.  Retry logic is removed.\n\n* Preflush needs to be issued to all member devices but FUA writes can\n  be handled the same way as other writes - their processing can be\n  deferred to request_queue of member devices.  md_barrier_request()\n  is renamed to md_flush_request() and simplified accordingly.\n\nFor linear, raid0 and multipath, the core changes are enough.  raid1,\n5 and 10 need the following conversions.\n\n* raid1: Handling of FLUSH/FUA bio\u0027s can simply be deferred to\n  request_queues of member devices.  Barrier related logic removed.\n\n* raid5: Queue draining logic dropped.  FUA bit is propagated through\n  biodrain and stripe resconstruction such that all the updated parts\n  of the stripe are written out with FUA writes if any of the dirtying\n  writes was FUA.  preread_active_stripes handling in make_request()\n  is updated as suggested by Neil Brown.\n\n* raid10: FUA bit needs to be propagated to write clones.\n\nlinear, raid0, 1, 5 and 10 tested.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReviewed-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.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"

      "message": "md: support barrier requests on all personalities.\n\nPreviously barriers were only supported on RAID1.  This is because\nother levels requires synchronisation across all devices and so needed\na different approach.\nHere is that approach.\n\nWhen a barrier arrives, we send a zero-length barrier to every active\ndevice.  When that completes - and if the original request was not\nempty -  we submit the barrier request itself (with the barrier flag\ncleared) and then submit a fresh load of zero length barriers.\n\nThe barrier request itself is asynchronous, but any subsequent\nrequest will block until the barrier completes.\n\nThe reason for clearing the barrier flag is that a barrier request is\nallowed to fail.  If we pass a non-empty barrier through a striping\nraid level it is conceivable that part of it could succeed and part\ncould fail.  That would be way too hard to deal with.\nSo if the first run of zero length barriers succeed, we assume all is\nsufficiently well that we send the request and ignore errors in the\nsecond run of barriers.\n\nRAID5 needs extra care as write requests may not have been submitted\nto the underlying devices yet.  So we flush the stripe cache before\nproceeding with the barrier.\n\nNote that the second set of zero-length barriers are submitted\nimmediately after the original request is submitted.  Thus when\na personality finds mddev-\u003ebarrier to be set during make_request,\nit should not return from make_request until the corresponding\nper-device request(s) have been queued.\n\nThat will be done in later patches.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\nReviewed-by: Andre Noll \u003cmaan@systemlinux.org\u003e\n"

      "message": "block: fix diskstats access\n\nThere are two variants of stat functions - ones prefixed with double\nunderbars which don\u0027t care about preemption and ones without which\ndisable preemption before manipulating per-cpu counters.  It\u0027s unclear\nwhether the underbarred ones assume that preemtion is disabled on\nentry as some callers don\u0027t do that.\n\nThis patch unifies diskstats access by implementing disk_stat_lock()\nand disk_stat_unlock() which take care of both RCU (for partition\naccess) and preemption (for per-cpu counter access).  diskstats access\nshould always be enclosed between the two functions.  As such, there\u0027s\nno need for the versions which disables preemption.  They\u0027re removed\nand double underbars ones are renamed to drop the underbars.  As an\nextra argument is added, there\u0027s no danger of using the old version\nunconverted.\n\ndisk_stat_lock() uses get_cpu() and returns the cpu index and all\ndiskstat functions which access per-cpu counters now has @cpu\nargument to help RT.\n\nThis change adds RCU or preemption operations at some places but also\ncollapses several preemption ops into one at others.  Overall, the\nperformance difference should be negligible as all involved ops are\nvery lightweight per-cpu ones.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n"

We can create a separate \"historical\" git\narchive of that later if we want to, and in the meantime it\u0027s about\n3.2GB when imported into git - space that would just make the early\ngit days unnecessarily complicated, when we don\u0027t have a lot of good\ninfrastructure for it.\n\nLet it rip!\n"
