Linus Torvalds 1f7563f743 SCSI sg on 20190709
This topic branch covers a fundamental change in how our sg lists are
 allocated to make mq more efficient by reducing the size of the
 preallocated sg list.  This necessitates a large number of driver
 changes because the previous guarantee that if a driver specified
 SG_ALL as the size of its scatter list, it would get a non-chained
 list and didn't need to bother with scatterlist iterators is now
 broken and every driver *must* use scatterlist iterators.
 
 This was broken out as a separate topic because we need to convert all
 the drivers before pulling the trigger and unconverted drivers kept
 being found, necessitating a rebase.
