2012-12-06T13:33:02Z

The function bsg_goose_queue() does not have any in-tree callers, so let's remove it. Signed-off-by: Bart Van Assche Acked-by: Tejun Heo Signed-off-by: Jens Axboe

block: drop custom queue draining used by scsi_transport_{iscsi|fc}

2012-06-25T09:53:48Z

iscsi_remove_host() uses bsg_remove_queue() which implements custom queue draining. fc_bsg_remove() open-codes mostly identical logic. The draining logic isn't correct in that blk_stop_queue() doesn't prevent new requests from being queued - it just stops processing, so nothing prevents new requests to be queued after the logic determines that the queue is drained. blk_cleanup_queue() now implements proper queue draining and these custom draining logics aren't necessary. Drop them and use bsg_unregister_queue() + blk_cleanup_queue() instead.

block: add bsg helper library

2011-07-31T20:05:09Z

This moves the FC classes bsg code to the block layer and makes it a lib so that other classes like iscsi and SAS can use it. It is helpful because working with the request queue, bios, creating scatterlists, etc are a pain that the LLD does not have to worry about with normal IOs and should not have to worry about for bsg requests.
