Hi Linus,
Here are the target-pending updates for v4.13-rc1. Please go ahead and
pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next
Note there is a qla2xxx conflict with scsi.git as reported by SFR, which
should be straight-forward to resolve:
https://lkml.org/lkml/2017/6/28/45
Note there was two additional qla2xxx conflicts with scsi.git:
https://lkml.org/lkml/2017/7/3/22
https://lkml.org/lkml/2017/7/3/23
However, the patch that caused these has since been reverted:
55dd8cf Revert "qla2xxx: Fix incorrect tcm_qla2xxx_free_cmd use during TMR ABORT"
as it caused other problems, so these conflicts can be ignored.
Attached is v4.13-rc1-resolution.diff if there are any questions wrt to
how the resolution should look. Adding Himanshu + Quinn CC'.
That said, 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)
Thank you,
