Merge patch series "convert SCSI to atomic queue limits, part 1 (v3)"

Browse Source 
Christoph Hellwig <hch@lst.de> says:

Hi all,

this series converts the SCSI midlayer and LLDDs to use atomic queue
limits API.  It is pretty straight forward, except for the mpt3mr
driver which does really weird and probably already broken things by
setting limits from unlocked device iteration callbacks.

I will probably defer the (more complicated) ULD changes to the next
merge window as they would heavily conflict with Damien's zone write
plugging series.  With that the series could go in through the SCSI
tree if Jens' ACKs the core block layer bits.
