Changed in V2:
- Addressed the comment from Ming Lei, thanks.

Changed in V3:
- Switch to memalloc_noio_save/restore from Christoph's comment, thanks.

Changed in V4:
- Switch back to v2 by remove the memalloc_ stuff
- With a small fix by making all the gfp flags to BLK_MQ_GFP_FLAGS in
blk_mq_alloc_rq_map where the NOIO is needed.

Xiubo Li (2):
  blk-mq: Avoid memory reclaim when allocating request map
  blk-mq: use BLK_MQ_GFP_FLAGS macro instead
