block: unify request timeout handling 2008-10-09T06:56:13+00:00 Jens Axboe jens.axboe@oracle.com 2008-09-14T12:55:09+00:00 242f9dcb8ba6f68fcd217a119a7648a4f69290e9 Right now SCSI and others do their own command timeout handling. Move those bits to the block layer. Instead of having a timer per command, we try to be a bit more clever and simply have one per-queue. This avoids the overhead of having to tear down and setup a timer for each command, so it will result in a lot less timer fiddling.
