Linus Torvalds fd2b2c57ec SCSI fixes on 20170725 ... Three small fixes. The transfer size fixes are actually correcting some performance drops on the hpsa and smartpqi cards. The cards actually have an internal cache for request speed up but bypass it for transfers > 1MB. Since 4.3 the efficiency of our merges has rendered the cache mostly unused, so limit transfers to under 1MB to recover the cache boost. Signed-off-by: James E.J.
