Subject: [GIT PULL] Block pull request for- 4.11-rc1
Hi Linus,
This is the collected pull request for 4.11 for the block core and
drivers. It's really two different branches:
for-4.11/block-signed
for-4.11/next-signed
for-4.11/next exists because some of Christoph's patch series were based
on patches that were added after for-4.11/block was forked off, which
would have caused needless merge pain. So for-4.11/next was forked off
v4.10-rc5, with for-4.11/block pulled in. Feel free to pull each of
these in succession instead of this pre-merged branch. Note that if you
do opt for pulling the two branches, for-4.11/block will throw a trivial
merge conflict in block/blk-mq.c, where you need to delete a function.
for-4.11/next merges cleanly, HOWEVER, a commit that was added in
mainline since v4.10-rc5 (f2e767bb5d6e) adds a line of code that is no
longer valid with the changes in for-4.11/next. Hence, if you do pull in
separately, you'll want to --no-commit and edit:
drivers/scsi/mpt3sas/mpt3sas_scsih.c
to fix up that one line, like I did in the for-4.11/linus-merge branch.
With that said, this pull request contains:
- blk-mq scheduling framework from me and Omar, with a port of the
deadline scheduler for this framework. A port of BFQ from Paolo
is in the works, and should be ready for 4.12.
- Various fixups and improvements to the above scheduling framework
from Omar, Paolo, Bart, me, others.
- Cleanup of the exported sysfs blk-mq data into debugfs, from
Omar. This allows us to export more information that helps
debug hangs or performance issues, without cluttering or
abusing the sysfs API.
- Fixes for the sbitmap code, the scalable bitmap code that was
migrated from blk-mq, from Omar.
- Removal of the BLOCK_PC support in struct request, and refactoring of
carrying SCSI payloads in the block layer. This cleans up the code
nicely, and enables us to kill the SCSI specific parts of struct
request, shrinking it down nicely. From Christoph mainly, with help
from Hannes.
- Support for ranged discard requests and discard merging, also from
Christoph.
- Support for OPAL in the block layer, and for NVMe as well. Mainly
from Scott Bauer, with fixes/updates from various others folks.
- Error code fixup for gdrom from Christophe.
- cciss pci irq allocation cleanup from Christoph.
- Making the cdrom device operations read only, from Kees Cook.
- Fixes for duplicate bdi registrations and bdi/queue life time
problems from Jan and Dan.
- Set of fixes and updates for lightnvm, from Matias and Javier.
- A few fixes for nbd from Josef, using idr to name devices and
a workqueue deadlock fix on receive. Also marks Josef as the
current maintainer of nbd.
- Fix from Josef, overwriting queue settings when the number of
hardware queues is updated for a blk-mq device.
- NVMe fix from Keith, ensuring that we don't repeatedly mark
and IO aborted, if we didn't end up aborting it.
- SG gap merging fix from Ming Lei for block.
- Loop fix also from Ming, fixing a race and crash between setting
loop status and IO.
- Two block race fixes from Tahsin, fixing request list iteration
and fixing a race between device registration and udev device add
notifiations.
- Double free fix from cgroup writeback, from Tejun.
- Another double free fix in blkcg, from Hou Tao.
- Partition overflow fix for EFI from Alden Tondettar.
Please pull! Either this pre-merged branch:
git://git.kernel.dk/linux-block.git for-4.11/linus-merge-signed
or
git://git.kernel.dk/linux-block.git for-4.11/block-signed
git://git.kernel.dk/linux-block.git for-4.11/next-signed
in that order. All branches are signed tags.
