Linus Torvalds bdb39c9509 SCSI misc on 20210219
This series consists of the usual driver updates (ufs, ibmvfc,
 qla2xxx, hisi_sas, pm80xx) plus the removal of the gdth driver (which
 is bound to cause conflicts with a trivial change somewhere).  The
 only big major rework of note is the one from Hannes trying to clean
 up our result handling code in the drivers to make it consistent.

SCSI Kernel Parameters
======================
See Documentation/admin-guide/kernel-parameters.rst for general information on
specifying module parameters.
This document may not be entirely up to date and comprehensive. The command
``modinfo -p ${modulename}`` shows a current list of all parameters of a loadable
module. Loadable modules, after being loaded into the running kernel, also
reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
parameters may be changed at runtime by the command
``echo -n ${value} > /sys/module/${modulename}/parameters/${parm}``.
