[RFC PATCH 18/21] nvme-core: use lib tagset init helper for I/O q

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use the block layer helper to initialize the common fields of 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 the code repetation of
the inialization code of the tag set in current block drivers and any
future ones.
