During suspending or resuming, SCSI issues internal command which\n gets deferred and requeued for some reason. As the command is\n issued after the IO barrier in #1, ordered requeueing code puts the\n request after IO barrier sequence.\n\n4. The device is ready to process requests again but still is in\n quiesced state and the first request of the queue isn\u0027t\n REQ_PREEMPT, so command processing is deadlocked -\n suspending/resuming waits for the issued request to complete while\n the request can\u0027t be processed till device is put back into\n running state by resuming.\n\nThis can be fixed by always putting !fs requests at the front when\nrequeueing.\n\nThe following thread reports this deadlock.\n\n http://thread.gmane.org/gmane.linux.kernel/537473\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nAcked-by: David Greaves \u003cdavid@dgreaves.com\u003e\nAcked-by: Jeff Garzik \u003cjeff@garzik.org\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "8ce7ad7b2d11fae2c3d285a6a0caea9322c0b8fc", "tree": "87d7423635821dae9f26d14c62f3314ec7bb3b17", "parents": [ "86ce18d7b7925bfd6b64c061828ca2a857ee83b8" ], "author": { "name": "Kristen Carlson Accardi", "email": "kristen.c.accardi@intel.com", "time": "Wed May 23 13:57:38 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 23 20:14:12 2007 -0700" }, "message": "genhd: send async notification on media change\n\nSend an uevent to user space to indicate that a media change event has\noccurred.\n\nSigned-off-by: Kristen Carlson Accardi \u003ckristen.c.accardi@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "86ce18d7b7925bfd6b64c061828ca2a857ee83b8", "tree": "b753b7fd6d195aa7ed9eebc5a3917c5f20786260", "parents": [ "352823160613b65fdaa558be486720a71f75ed86" ], "author": { "name": "Kristen Carlson Accardi", "email": "kristen.c.accardi@intel.com", "time": "Wed May 23 13:57:38 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 23 20:14:11 2007 -0700" }, "message": "genhd: expose AN to user space\n\nAllow user space to determine if a disk supports Asynchronous Notification of\nmedia changes.

Currently CFQ uses a\ndoubly linked list per priority level for sorting and service uses.\nKill those lists and maintain an rbtree of cfq_queue\u0027s, sorted by when\nto service them.\n\nThis unfortunately means that the ionice levels aren\u0027t as strong\nanymore, will work on improving those later. We only scale the slice\ntime now, not the number of times we service. This means that latency\nis better (for all priority levels), but that the distinction between\nthe highest and lower levels aren\u0027t as big.\n\nThe diffstat speaks for itself.\n\n cfq-iosched.c | 363 +++++++++++++++++---------------------------------\n 1 file changed, 125 insertions(+), 238 deletions(-)\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "1afba0451c83cbff622a08f2d86fbb2e680dfd5f", "tree": "7da7b97114b73d6d9788cf8663cd3aa28433c0dd", "parents": [ "6d048f5310aa2dda2b5acd947eab3598c25e269f" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Apr 17 12:47:55 2007 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Mon Apr 30 09:01:21 2007 +0200" }, "message": "cfq-iosched: minor updates\n\n- Move the queue_new flag clear to when the queue is selected\n- Only select the non-first queue in cfq_get_best_queue(), if there\u0027s\n a substantial difference between the best and first.\n- Get rid of -\u003ebusy_rr\n- Only select a close cooperator, if the current queue is known to take\n a while to \"think\".\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "6d048f5310aa2dda2b5acd947eab3598c25e269f", "tree": "4f0dbcd21b82dd015a908139fb4de3601b3d834a", "parents": [ "1e3335de05da3dfbe48b8caa03db1834a2133256" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Wed Apr 25 12:44:27 2007 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Mon Apr 30 09:01:21 2007 +0200" }, "message": "cfq-iosched: development update\n\n- Implement logic for detecting cooperating processes, so we\n choose the best available queue whenever possible.\n\n- Improve residual slice time accounting.\n\n- Remove dead code: we no longer see async requests coming in on\n sync queues.
