<torvalds@linux-foundation.org> # Date: Wed Aug 15 22:06:26 2018 -0700 # # 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
