Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This is mostly updates to the usual drivers: mpt3sas, lpfc, qla2xxx,
hisi_sas, smartpqi, megaraid_sas, arcmsr.
In addition, with the continuing absence of Nic we have target updates
for tcmu and target core (all with reviews and acks).
The biggest observable change is going to be that we're (again) trying
to switch to mulitqueue as the default (a user can still override the
setting on the kernel command line).
Other major core stuff is the removal of the remaining Microchannel
drivers, an update of the internal timers and some reworks of
completion and result handling"
