Hi Linus,
A small collection of fixes for the current rc series. It contains:
- Two small blk-mq patches from Rob Elliott, cleaning up error case at
init time.
- A fix from Ming Lei, fixing SG merging for blk-mq where
QUEUE_FLAG_SG_NO_MERGE is the default.
- A dev_t minor lifetime fix from Keith, fixing an issue where a minor
might be reused before all references to it were gone.
- Fix from Alan Stern where an unbalanced queue bypass caused SCSI some
headaches when it does a series of add/del on devices without fully
registrering the queue.
- A fix from me for improving the scaling of tag depth in blk-mq if we
are short on memory.
