Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI updates from James Bottomley:
 "This consists of the usual driver updates (ufs, smartpqi, lpfc,
  target, megaraid_sas, hisi_sas, qla2xxx) and minor updates and bug
  fixes.

  Notable core changes are the removal of scsi->tag which caused some
  churn in obsolete drivers and a sweep through all drivers to call
  scsi_done() directly instead of scsi->done() which removes a pointer
  indirection from the hot path and a move to register core sysfs files
  earlier, which means they're available to KOBJ_ADD processing, which
  necessitates switching all drivers to using attribute groups"

		What: /sys/class/fc/fc_udev_device/appid_store
		Date: Aug 2021
		Contact: Muneendra Kumar <muneendra.kumar@broadconm.com>
		Description:
		This interface allows an admin to set an FC application
		identifier in the blkcg associated with a cgroup id. The
		identifier is typically a UUID that is associated with
		an application or logical entity such as a virtual
		machine or container group. The application or logical
		entity utilizes a block device via the cgroup id.
		FC adapter drivers may query the identifier and tag FC
		traffic based on the identifier. FC host and FC fabric
		entities can utilize the application id and FC traffic
		tag to identify traffic sources.

		The interface expects a string "<cgroupid>:<appid>" where:
		<cgroupid> is inode of the cgroup in hexadecimal
		<appid> is user provided string upto 128 characters
		in length.

		If an appid_store is done for a cgroup id that already
		has an appid set, the new value will override the
		previous value.

		If an admin wants to remove an FC application identifier
		from a cgroup, an appid_store should be done with the
		following string: "<cgroupid>:"
