[RFC PATCH 00/21] block: add and use init tagset helper

[Chaitanya Kulkarni]

Hi,

Add and use the helper to initialize the common fields of the tag_set
such as blk_mq_ops, number of h/w queues, queue depth, command size,
numa_node, timeout, BLK_MQ_F_XXX flags, driver data. This initialization
is spread all over the block drivers. This avoids repetation of
inialization code of the tag set in current block drivers and any future
ones.

P.S. I'm aware of the EXPORT_SYMBOL_GPL() checkpatch warn just to make
get some feedback to so I can remove the RFC tag.
