The racing between callbacks can lead to corruption of exception\nstore and it can also mean that exception store callbacks are called twice\nfor the same exception - a likely reason for crashes reported inside\npending_complete() / remove_exception().\n\nThis patch fixes two problems:\n\n1. job-\u003efn being called from the thread that submitted the job (see above).\n\n- Fix: hand over the completion callback to the kcopyd thread.\n\n2. job-\u003efn(read_err, write_err, job-\u003econtext); in segment_complete\nreports the error of the last subjob, not the union of all errors.\n\n- Fix: pass job-\u003ewrite_err to the callback to report all error bits\n  (it is done already in run_complete_job)\n\nCc: stable@kernel.org\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n"

      "message": "dm: unplug queues in threads\n\nRemove an avoidable 3ms delay on some dm-raid1 and kcopyd I/O.\n\nIt is specified that any submitted bio without BIO_RW_SYNC flag may plug the\nqueue (i.e. block the requests from being dispatched to the physical device).\n\nThe queue is unplugged when the caller calls blk_unplug() function. Usually, the\nsequence is that someone calls submit_bh to submit IO on a buffer. The IO plugs\nthe queue and waits (to be possibly joined with other adjacent bios). Then, when\nthe caller calls wait_on_buffer(), it unplugs the queue and submits the IOs to\nthe disk.\n\nThis was happenning:\n\nWhen doing O_SYNC writes, function fsync_buffers_list() submits a list of\nbios to dm_raid1, the bios are added to dm_raid1 write queue and kmirrord is\nwoken up.\n\nfsync_buffers_list() calls wait_on_buffer().  That unplugs the queue, but\nthere are no bios on the device queue as they are still in the dm_raid1 queue.\n\nwait_on_buffer() starts waiting until the IO is finished.\n\nkmirrord is scheduled, kmirrord takes bios and submits them to the devices.\n\nThe submitted bio plugs the harddisk queue but there is no one to unplug it.\n(The process that called wait_on_buffer() is already sleeping.)\n\nSo there is a 3ms timeout, after which the queues on the harddisks are\nunplugged and requests are processed.\n\nThis 3ms timeout meant that in certain workloads (e.g. O_SYNC, 8kb writes),\ndm-raid1 is 10 times slower than md raid1.\n\nEvery time we submit something asynchronously via dm_io, we must unplug the\nqueue actually to send the request to the device.\n\nThis patch adds an unplug call to kmirrord - while processing requests, it keeps\nthe queue plugged (so that adjacent bios can be merged); when it finishes\nprocessing all the bios, it unplugs the queue to submit the bios.\n\nIt also fixes kcopyd which has the same potential problem. All kcopyd requests\nare submitted with BIO_RW_SYNC.\n\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\nAcked-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n"
