Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe:
"A collection of fixes from the past few weeks that should go into 4.5.
This contains:
- Overflow fix for sysfs discard show function from Alan.
- A stacking limit init fix for max_dev_sectors, so we don't end up
artificially capping some use cases. From Keith.
- Have blk-mq proper end unstarted requests on a dying queue, instead
of pushing that to the driver. From Keith.
- NVMe:
- Update to Kconfig description for NVME_SCSI, since it was
vague and having it on is important for some SUSE distros.
From Christoph.
- Set of fixes from Keith, around surprise removal. Also kills
the no-merge flag, so it supports merging.
- Set of fixes for lightnvm from Matias, Javier, and Wenwei.
- Fix null_blk oops when asked for lightnvm, but not available. From
Matias.
- Copy-to-user EINTR fix from Hannes, fixing a case where SG_IO fails
if interrupted by a signal.
- Two floppy fixes from Jiri, fixing signal handling and blocking
open.
- A use-after-free fix for O_DIRECT, from Mike Krinkin.
- A block module ref count fix from Roman Pen.
- An fs IO wait accounting fix for O_DSYNC from Stephane Gasparini.
- Smaller reallo fix for xen-blkfront from Bob Liu.
- Removal of an unused struct member in the deadline IO scheduler,
from Tahsin.
- Also from Tahsin, properly initialize inode struct members
associated with cgroup writeback, if enabled.
- From Tejun, ensure that we keep the superblock pinned during cgroup
writeback"
