Linus Torvalds eda809aef5 SCSI fixes on 20210101
This is a load of driver fixes (12 ufs, 1 mpt3sas, 1 cxgbi).  The big
 core two fixes are for power management ("block: Do not accept any
 requests while suspended" and "block: Fix a race in the runtime power
 management code") which finally sorts out the resume problems we've
 occasionally been having.  To make the resume fix, there are seven
 necessary precursors which effectively renames REQ_PREEMPT to REQ_PM,
 so every "special" request in block is automatically a power
 management exempt one.  All of the non-PM preempt cases are removed
 except for the one in the SCSI Parallel Interface (spi) domain
 validation which is a genuine case where we have to run requests at
 high priority to validate the bus so this becomes an autopm get/put
 protected request.
