Pull SCSI target updates from Nicholas Bellinger:
"It's been usually busy for summer, with most of the efforts centered
around TCMU developments and various target-core + fabric driver bug
fixing activities. Not particularly large in terms of LoC, but lots of
smaller patches from many different folks.
The highlights include:
- ibmvscsis logical partition manager support (Michael Cyr + Bryant
Ly)
- Convert target/iblock WRITE_SAME to blkdev_issue_zeroout (hch +
nab)
- Add support for TMR percpu LUN reference counting (nab)
- Fix a potential deadlock between EXTENDED_COPY and iscsi shutdown
(Bart)
- Fix COMPARE_AND_WRITE caw_sem leak during se_cmd quiesce (Jiang Yi)
- Fix TMCU module removal (Xiubo Li)
- Fix iser-target OOPs during login failure (Andrea Righi + Sagi)
- Breakup target-core free_device backend driver callback (mnc)
- Perform TCMU add/delete/reconfig synchronously (mnc)
- Fix TCMU multiple UIO open/close sequences (mnc)
- Fix TCMU CHECK_CONDITION sense handling (mnc)
- Fix target-core SAM_STAT_BUSY + TASK_SET_FULL handling (mnc + nab)
- Introduce TYPE_ZBC support in PSCSI (Damien Le Moal)
- Fix possible TCMU memory leak + OOPs when recalculating cmd base
size (Xiubo Li + Bryant Ly + Damien Le Moal + mnc)
- Add login_keys_workaround attribute for non RFC initiators (Robert
LeBlanc + Arun Easi + nab)"
* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (68 commits)

tcmu: fix sense handling during completion
target: add helper to copy sense to se_cmd buffer
target: do not require a transport_complete for SCF_TRANSPORT_TASK_SENSE
target: make device_mutex and device_list static
tcmu: Fix flushing cmd entry dcache page
tcmu: fix multiple uio open/close sequences
tcmu: drop configured check in destroy
