block: adjust tagging function queue bit locking 2008-05-07T07:27:43+00:00 Jens Axboe jens.axboe@oracle.com 2008-05-07T07:27:43+00:00 aa94b5371f6f898558d9fa5690cc6e4bf917a572 For most initialization purposes, calling blk_queue_init_tags() without the queue lock held is OK. Only if called for resizing an existing map must the lock be held. Ditto for tag cleanup, the maps are reference counted. So switch the general queue flag setting to the unlocked variant, but retain the locked variant for resizing. Signed-off-by: Jens Axboe <jens.axboe@oracle.com> 
For most initialization purposes, calling blk_queue_init_tags() without
the queue lock held is OK. Only if called for resizing an existing map
must the lock be held. Ditto for tag cleanup, the maps are reference
counted.

So switch the general queue flag setting to the unlocked variant, but
retain the locked variant for resizing.
