[PATCH 0/7] dm: add full blk-mq support to request-based DM

2015-03-11 Thread Mike Snitzer
This patchset updates request-based DM (used exclussively by DM multipath) to support blk-mq I/O path or the old ->request_fn I/O path -- the default is still the old ->request_fn I/O path. Like was done for SCSI, I've exposed a dm-mod.ko 'use_blk_mq' module parameter and a CONFIG_DM_MQ_DEFAULT.
