From 24d2f90309b23f2cfe016b2aebc5f0d6e01c57fd Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 15 Apr 2014 14:14:00 -0600 Subject: blk-mq: split out tag initialization, support shared tags Add a new blk_mq_tag_set structure that gets set up before we initialize the queue. A single blk_mq_tag_set structure can be shared by multiple queues. Signed-off-by: Christoph Hellwig Modular export of blk_mq_{alloc,free}_tagset added by me.
