barrier support for request-based dm.\n\nCORE DESIGN\n\nThe design is basically same as bio-based dm, which emulates barrier\nby mapping empty barrier bios before/after a barrier I/O.\nBut request-based dm has been using struct request_queue for I/O\nqueueing, so the block-layer\u0027s barrier mechanism can be used.\n\no Summary of the block-layer\u0027s behavior (which is depended by dm-core)\n Request-based dm uses QUEUE_ORDERED_DRAIN_FLUSH ordered mode for\n I/O barrier. It means that when an I/O requiring barrier is found\n in the request_queue, the block-layer makes pre-flush request and\n post-flush request just before and just after the I/O respectively.\n\n After the ordered sequence starts, the block-layer waits for all\n in-flight I/Os to complete, then gives drivers the pre-flush request,\n the barrier I/O and the post-flush request one by one.\n It means that the request_queue is stopped automatically by\n the block-layer until drivers complete each sequence.\n\no dm-core\n For the barrier I/O, treats it as a normal I/O, so no additional\n code is needed.\n\n For the pre/post-flush request, flushes caches by the followings:\n 1. Make the number of empty barrier requests required by target\u0027s\n num_flush_requests, and map them (dm_rq_barrier()).\n 2. Waits for the mapped barriers to complete (dm_rq_barrier()).\n If error has occurred, save the error value to md-\u003ebarrier_error\n (dm_end_request()).\n (*) Basically, the first reported error is taken.\n But -EOPNOTSUPP supersedes any error and DM_ENDIO_REQUEUE\n follows.\n 3. Requeue the pre/post-flush request if the error value is\n DM_ENDIO_REQUEUE. Otherwise, completes with the error value\n (dm_rq_barrier_work()).\n The pre/post-flush work above is done in the kernel thread (kdmflush)\n context, since memory allocation which might sleep is needed in\n dm_rq_barrier() but sleep is not allowed in dm_request_fn(), which is\n an irq-disabled context.\n Also, clones of the pre/post-flush request share an original, so\n such clones can\u0027t be completed using the softirq context.\n Instead, complete them in the context of underlying device drivers.\n It should be safe since there is no I/O dispatching during\n the completion of such clones.\n\n For suspend, the workqueue of kdmflush needs to be flushed after\n the request_queue has been stopped. Otherwise, the next flush work\n can be kicked even after the suspend completes.\n\nTARGET INTERFACE\n\nNo new interface is added.\nJust use the existing num_flush_requests in struct target_type\nas same as bio-based dm.\n\nSigned-off-by: Kiyoshi Ueda \u003ck-ueda@ct.jp.nec.com\u003e\nSigned-off-by: Jun\u0027ichi Nomura \u003cj-nomura@ce.jp.nec.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "980691e5f3a1b5ebbb2d34014e028fd7f1c6e4fb", "tree": "a4d593cf3818a54c41e6a4115cad63128b738c0b", "parents": [ "11a68244e16b0c35e122dd55b4e7c595e0fb67a1" ], "author": { "name": "Kiyoshi Ueda", "email": "k-ueda@ct.jp.nec.com", "time": "Thu Dec 10 23:52:17 2009 +0000" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Thu Dec 10 23:52:17 2009 +0000" }, "message": "dm: move dm_end_request\n\nThis patch moves dm_end_request() to make the next patch more readable.\nNo functional change.\n\nSigned-off-by: Kiyoshi Ueda \u003ck-ueda@ct.jp.nec.com\u003e\nSigned-off-by: Jun\u0027ichi Nomura \u003cj-nomura@ce.jp.nec.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "11a68244e16b0c35e122dd55b4e7c595e0fb67a1", "tree": "ac982eb9abf6eca76ae35a9e0900323b54bb3ab9", "parents": [ "b4324feeae304ae39e631a254d238a7d63be004b" ], "author": { "name": "Kiyoshi Ueda", "email": "k-ueda@ct.jp.nec.com", "time": "Thu Dec 10 23:52:17 2009 +0000" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Thu Dec 10 23:52:17 2009 +0000" }, "message": "dm: refactor request based completion functions\n\nThis patch factors out the clone completion code, dm_done(),\nfrom dm_softirq_done() in preparation for a subsequent patch.\nNo functional change.\n\ndm_done() will be used in barrier completion, which can\u0027t use and\ndoesn\u0027t need softirq.
