Linus Torvalds 9105b8aa50 SCSI fixes on 20181221 
This is two simple target fixes and one discard related I/O starvation
 problem in sd.  The discard problem occurs because the discard page
 doesn't have a mempool backing so if the allocation fails due to
 memory pressure, we then lose the forward progress we require if the
 writeout is on the same device.  The fix is to back it with a mempool.
