      "message": "tracing/events: convert block trace points to TRACE_EVENT()\n\nTRACE_EVENT is a more generic way to define tracepoints. Doing so adds\nthese new capabilities to this tracepoint:\n\n  - zero-copy and per-cpu splice() tracing\n  - binary tracing without printf overhead\n  - structured logging records exposed under /debug/tracing/events\n  - trace events embedded in function tracer output and other plugins\n  - user-defined, per tracepoint filter expressions\n  ...\n\nCons:\n\n  - no dev_t info for the output of plug, unplug_timer and unplug_io events.\n    no dev_t info for getrq and sleeprq events if bio \u003d\u003d NULL.\n    no dev_t info for rq_abort,...,rq_requeue events if rq-\u003erq_disk \u003d\u003d NULL.\n\n    This is mainly because we can\u0027t get the deivce from a request queue.\n    But this may change in the future.\n\n  - A packet command is converted to a string in TP_assign, not TP_print.\n    While blktrace do the convertion just before output.\n\n    Since pc requests should be rather rare, this is not a big issue.\n\n  - In blktrace, an event can have 2 different print formats, but a TRACE_EVENT\n    has a unique format, which means we have some unused data in a trace entry.\n\n    The overhead is minimized by using __dynamic_array() instead of __array().\n\nI\u0027ve benchmarked the ioctl blktrace vs the splice based TRACE_EVENT tracing:\n\n      dd                   dd + ioctl blktrace       dd + TRACE_EVENT (splice)\n1     7.36s, 42.7 MB/s     7.50s, 42.0 MB/s          7.41s, 42.5 MB/s\n2     7.43s, 42.3 MB/s     7.48s, 42.1 MB/s          7.43s, 42.4 MB/s\n3     7.38s, 42.6 MB/s     7.45s, 42.2 MB/s          7.41s, 42.5 MB/s\n\nSo the overhead of tracing is very small, and no regression when using\nthose trace events vs blktrace.\n\nAnd the binary output of TRACE_EVENT is much smaller than blktrace:\n\n # ls -l -h\n -rw-r--r-- 1 root root 8.8M 06-09 13:24 sda.blktrace.0\n -rw-r--r-- 1 root root 195K 06-09 13:24 sda.blktrace.1\n -rw-r--r-- 1 root root 2.7M 06-09 13:25 trace_splice.out\n\nFollowing are some comparisons between TRACE_EVENT and blktrace:\n\nplug:\n  kjournald-480   [000]   303.084981: block_plug: [kjournald]\n  kjournald-480   [000]   303.084981:   8,0    P   N [kjournald]\n\nunplug_io:\n  kblockd/0-118   [000]   300.052973: block_unplug_io: [kblockd/0] 1\n  kblockd/0-118   [000]   300.052974:   8,0    U   N [kblockd/0] 1\n\nremap:\n  kjournald-480   [000]   303.085042: block_remap: 8,0 W 102736992 + 8 \u003c- (8,8) 33384\n  kjournald-480   [000]   303.085043:   8,0    A   W 102736992 + 8 \u003c- (8,8) 33384\n\nbio_backmerge:\n  kjournald-480   [000]   303.085086: block_bio_backmerge: 8,0 W 102737032 + 8 [kjournald]\n  kjournald-480   [000]   303.085086:   8,0    M   W 102737032 + 8 [kjournald]\n\ngetrq:\n  kjournald-480   [000]   303.084974: block_getrq: 8,0 W 102736984 + 8 [kjournald]\n  kjournald-480   [000]   303.084975:   8,0    G   W 102736984 + 8 [kjournald]\n\n  bash-2066  [001]  1072.953770:   8,0    G   N [bash]\n  bash-2066  [001]  1072.953773: block_getrq: 0,0 N 0 + 0 [bash]\n\nrq_complete:\n  konsole-2065  [001]   300.053184: block_rq_complete: 8,0 W () 103669040 + 16 [0]\n  konsole-2065  [001]   300.053191:   8,0    C   W 103669040 + 16 [0]\n\n  ksoftirqd/1-7   [001]  1072.953811:   8,0    C   N (5a 00 08 00 00 00 00 00 24 00) [0]\n  ksoftirqd/1-7   [001]  1072.953813: block_rq_complete: 0,0 N (5a 00 08 00 00 00 00 00 24 00) 0 + 0 [0]\n\nrq_insert:\n  kjournald-480   [000]   303.084985: block_rq_insert: 8,0 W 0 () 102736984 + 8 [kjournald]\n  kjournald-480   [000]   303.084986:   8,0    I   W 102736984 + 8 [kjournald]\n\nChangelog from v2 -\u003e v3:\n\n- use the newly introduced __dynamic_array().\n\nChangelog from v1 -\u003e v2:\n\n- use __string() instead of __array() to minimize the memory required\n  to store hex dump of rq-\u003ecmd().\n\n- support large pc requests.\n\n- add missing blk_fill_rwbs_rq() in block_rq_requeue TRACE_EVENT.\n\n- some cleanups.\n\nSigned-off-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nLKML-Reference: \u003c4A2DF669.5070905@cn.fujitsu.com\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n"

      "message": "md/raid5 - avoid deadlocks in get_active_stripe during reshape\n\nmd has functionality to \u0027quiesce\u0027 and array so that all pending\nIO completed and no new IO starts.  This is used to achieve a\nstable state before making internal changes.\n\nCurrently this quiescing applies equally to normal IO, resync\nIO, and reshape IO.\nHowever there is a problem with applying it to reshape IO.\nReshape can have multiple \u0027stripe_heads\u0027 that must be active together.\nIf the quiesce come between allocating the first and the last of\nsuch a collection, then we deadlock, as the last will not be allocated\nuntil the quiesce is lifted, the quiesce will not be lifted until the\nfirst (which has been allocated) gets used, and that first cannot be\nused until the last is allocated.\n\nIt is not necessary to inhibit reshape IO when a quiesce is\nrequested.  Those places in the code that require a full quiesce will\nensure the reshape thread is not running at all.\n\nSo allow reshape requests to get access to new stripe_heads without\nbeing blocked by a \u0027quiesce\u0027.\n\nThis only affects in-place reshapes (i.e. where the array does not\ngrow or shrink) and these are only newly supported.  So this patch is\nnot needed in earlier kernels.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\n"

      "message": "md: update sync_completed and reshape_position even more often.\n\nThere are circumstances when a user-space process might need to\n\"oversee\" a resync/reshape process.  For example when doing an\nin-place reshape of a raid5, it is prudent to take a backup of each\nsection before reshaping it as this is the only way to provide\nsafety against an unplanned shutdown (i.e. crash/power failure).\n\nThe sync_max sysfs value can be used to stop the resync from\nadvancing beyond a particular point.\nSo user-space can:\n  suspend IO to the first section and back it up\n  set \u0027sync_max\u0027 to the end of the section\n  wait for \u0027sync_completed\u0027 to reach that point\n  resume IO on the first section and move on to the next section.\n\nHowever this process requires the kernel and user-space to run in\nlock-step which could introduce unnecessary delays.\n\nIt would be better if a \u0027double buffered\u0027 approach could be used with\nuserspace and kernel space working on different sections with the\n\u0027next\u0027 section always ready when the \u0027current\u0027 section is finished.\n\nOne problem with implementing this is that sync_completed is only\nguaranteed to be updated when the sync process reaches sync_max.\n(it is updated on a time basis at other times, but it is hard to rely\non that).  This defeats some of the double buffering.\n\nWith this patch, sync_completed (and reshape_position) get updated as\nthe current position approaches sync_max, so there is room for\nuserspace to advance sync_max early without losing updates.\n\nTo be precise, sync_completed is updated when the current sync\nposition reaches half way between the current value of sync_completed\nand the value of sync_max.  This will usually be a good time for user\nspace to update sync_max.\n\nIf sync_max does not get updated, the updates to sync_completed\n(together with associated metadata updates) will occur at an\nexponentially increasing frequency which will get unreasonably fast\n(one update every page) immediately before the process hits sync_max\nand stops.  So the update rate will be unreasonably fast only for an\ninsignificant period of time.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\n"

(We must wait, otherwise it could be intermixed with\nfollowing requests.)\n\nErrors from the barrier request are recorded in a per-device barrier_error\nvariable. There may be only one barrier request in progress at once.\n\nFor now, the barrier request is converted to a non-barrier request when\nsending it to the underlying device.\n\nThis patch guarantees correct barrier behavior if the underlying device\ndoesn\u0027t perform write-back caching. The same requirement existed before\nbarriers were supported in dm.\n\nBottom layer barrier support (sending barriers by target drivers) and\nhandling devices with write-back caches will be done in further patches.\n\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n"
