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.
