      "message": "block: add blk-iopoll, a NAPI like approach for block devices\n\nThis borrows some code from NAPI and implements a polled completion\nmode for block devices. The idea is the same as NAPI - instead of\ndoing the command completion when the irq occurs, schedule a dedicated\nsoftirq in the hopes that we will complete more IO when the iopoll\nhandler is invoked. Devices have a budget of commands assigned, and will\nstay in polled mode as long as they continue to consume their budget\nfrom the iopoll softirq handler. If they do not, the device is set back\nto interrupt completion mode.\n\nThis patch holds the core bits for blk-iopoll, device driver support\nsold separately.\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n"

Once\ndisabled, there is a period of time when all the pageblocks are marked\nMOVABLE and the expectation is that they get marked UNMOVABLE at each call\nto __rmqueue_fallback().\n\nHowever, when MAX_ORDER is large the pageblocks do not change ownership\nbecause the normal criteria are not met.

This patch fixes the race.\n\nWhen the snapshot overflows, __invalidate_snapshot is called, which calls\nsnapshot store method drop_snapshot. It goes to persistent_drop_snapshot that\ncalls write_header. write_header constructs the new header in the \"area\"\nlocation.\n\nConcurrently, an existing kcopyd job may finish, call copy_callback\nand commit_exception method, that goes to persistent_commit_exception.\npersistent_commit_exception doesn\u0027t do locking, relying on the fact that\ncallbacks are single-threaded, but it can race with snapshot invalidation and\noverwrite the header that is just being written while the snapshot is being\ninvalidated.\n\nThe result of this race is a corrupted header being written that can\nlead to a crash on further reactivation (if chunk_size is zero in the\ncorrupted header).\n\nThe fix is to use separate memory areas for each.\n\nSee the bug: https://bugzilla.redhat.com/show_bug.cgi?id\u003d461506\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 log: userspace add luid to distinguish between concurrent log instances\n\nDevice-mapper userspace logs (like the clustered log) are\nidentified by a universally unique identifier (UUID).  This\nidentifier is used to associate requests from the kernel to\na specific log in userspace.  The UUID must be unique everywhere,\nsince multiple machines may use this identifier when communicating\nabout a particular log, as is the case for cluster logs.\n\nSometimes, device-mapper/LVM may re-use a UUID.  This is the\ncase during pvmoves, when moving from one segment of an LV\nto another, or when resizing a mirror, etc.  In these cases,\na new log is created with the same UUID and loaded in the\n\"inactive\" slot.  When a device-mapper \"resume\" is issued,\nthe \"live\" table is deactivated and the new \"inactive\" table\nbecomes \"live\".  (The \"inactive\" table can also be removed\nvia a device-mapper \u0027clear\u0027 command.)\n\nThe above two issues were colliding.  More than one log was being\ncreated with the same UUID, and there was no way to distinguish\nbetween them.  So, sometimes the wrong log would be swapped\nout during the exchange.\n\nThe solution is to create a locally unique identifier,\n\u0027luid\u0027, to go along with the UUID.  This new identifier is used\nto determine exactly which log is being referenced by the kernel\nwhen the log exchange is made.  The identifier is not\nuniversally safe, but it does not need to be, since\ncreate/destroy/suspend/resume operations are bound to a specific\nmachine; and these are the operations that make up the exchange.\n\nSigned-off-by: Jonathan Brassow \u003cjbrassow@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n"

      "message": "dm raid1: do not allow log_failure variable to unset after being set\n\nThis patch fixes a bug which was triggering a case where the primary leg\ncould not be changed on failure even when the mirror was in-sync.\n\nThe case involves the failure of the primary device along with\nthe transient failure of the log device.  The problem is that\nbios can be put on the \u0027failures\u0027 list (due to log failure)\nbefore \u0027fail_mirror\u0027 is called due to the primary device failure.\nNormally, this is fine, but if the log device failure is transient,\na subsequent iteration of the work thread, \u0027do_mirror\u0027, will\nreset \u0027log_failure\u0027.  The \u0027do_failures\u0027 function then resets\nthe \u0027in_sync\u0027 variable when processing bios on the failures list.\nThe \u0027in_sync\u0027 variable is what is used to determine if the\nprimary device can be switched in the event of a failure.  Since\nthis has been reset, the primary device is incorrectly assumed\nto be not switchable.\n\nThe case has been seen in the cluster mirror context, where one\nmachine realizes the log device is dead before the other machines.\nAs the responsibilities of the server migrate from one node to\nanother (because the mirror is being reconfigured due to the failure),\nthe new server may think for a moment that the log device is fine -\nthus resetting the \u0027log_failure\u0027 variable.\n\nIn any case, it is inappropiate for us to reset the \u0027log_failure\u0027\nvariable.
