[PATCH 0/5] blk-mq: Add a flag for reserved requests series

[John Garry]

In [0] I included "blk-mq: Add a flag for reserved requests" to identify
if a request is 'reserved' for special handling. Doing this is easier than
passing a 'reserved' arg to the blk_mq_ops callbacks. Indeed, only 1x
timeout implementation or blk-mq iter function actually uses the
'reserved' arg (or 3x if you count SCSI core and FNIC SCSI driver). So
this series drops the 'reserved' arg for these timeout and iter functions.
Christoph suggested that I try to upstream now.

About the SCSI changes, I can leave them in place if people prefer.

Based on following:
c13794dbe936 (block/for-5.20/block) block: Directly use ida_alloc()/free()
