 "The highlights this round include:

   - enable dual mode (initiator + target) qla2xxx operation. (Quinn +
     Himanshu)

   - add a framework for qla2xxx async fabric discovery. (Quinn +
     Himanshu)

   - enable iscsi PDU DDP completion offload in cxgbit/T6 NICs. (Varun)

   - fix target-core handling of aborted failed commands. (Bart)

   - fix a long standing target-core issue NULL pointer dereference with
     active I/O LUN shutdown. (Rob Millner + Bryant + nab)"

locking/atomic, kref: Add kref_read()

2017-01-14T10:37:18+00:00

Since we need to change the implementation, stop exposing internals.

Provide kref_read() to read the current reference count; typically
used for debug messages.

Kills two anti-patterns:

	atomic_read(&kref->refcount)
	kref->refcount.counter

Merge branch 'scsi-target-for-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/bvanassche/linux

2016-12-21T18:16:05+00:00

Pull scsi target cleanups from Bart Van Assche:
 "The changes here are:

   - a few small bug fixes for the iSCSI and user space target drivers.

   - minimize the target build time by about 30% by rearranging #include
     directives

   - fix the second argument passed to percpu_ida_alloc()

   - reduce the number of false positive warnings reported by sparse

  These patches pass Wu Fengguang's build bot tests and also the
  linux-next tests"

* 'scsi-target-for-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/bvanassche/linux:
  iscsi-target: Return error if unable to add network portal
  target: Fix spelling mistake and unwrap multi-line text
  target/iscsi: Fix double free in lio_target_tiqn_addtpg()
  target/user: Fix use-after-free of tcmu_cmds if they are expired
  target: Minimize #include directives
  target/user: Add an #include directive
  cxgbit: Add an #include directive
  ibmvscsi_tgt: Add two #include directives
  sbp-target: Add an #include directive
  qla2xxx: Add an #include directive
  configfs: Minimize #include directives
  usb: gadget: Fix second argument of percpu_ida_alloc()
  sbp-target: Fix second argument of percpu_ida_alloc()
  target/user: Fix a data type in tcmu_queue_cmd()
  target: Use NULL instead of 0 to represent a pointer

target: Minimize #include directives

2016-12-09T18:22:28+00:00

Remove superfluous #include directives from the include/target/*.h
files. Add missing #include directives to other *.h and *.c files.
Use forward declarations for structures where possible. This
change reduces the build time for make M=drivers/target on my
laptop from 27.1s to 18.7s or by about 30%.

scsi: libfc: Replace ->seq_release callback with function call

2016-11-08T22:29:56+00:00

The ->seq_release callback only ever had one implementation,
so call the function directly and drop the callback.
