Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending 

Pull scsi target fixes from Nicholas Bellinger:
 "Mostly minor fixes this time, including:

   - Add missing virtio-scsi -> TCM attribute conversion in vhost-scsi.
   - Fix persistent reservations write exclusive handling to allow
     readers for all registered I_T nexuses.
   - Drop arbitrary maximum I/O size limit in order to process I/Os
     larger than 4 MB, required for initiators that don't honor block
     limits EVPD.
   - Drop the now left-over fabric_max_sectors attribute"

* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  iscsi-target: Fix typos in enum cmd_flags_table
  MAINTAINERS: Add entry for iSER target driver
  target: Allow Write Exclusive non-reservation holders to READ
  target: Drop left-over fabric_max_sectors attribute
  target: Drop arbitrary maximum I/O size limit
  Documentation/target: Update fabric_ops to latest code
  vhost-scsi: Add missing virtio-scsi -> TCM attribute conversion
