The end_device and sas_host devices support BSG ioctls, but the
request_queue allocated for them isn't set up to allocate the struct
scsi_request payload. This leads to memory corruption in the call to
scsi_req_init() in bsg_map_hdr(), since it will memset past the end of
the allocated request. Fix it by setting ->cmd_size on the allocated
request_queue.

When a device gets removed, block device inode unhashed so that it is not
used anymore (bdget() will not find it anymore). Later when a new device
gets created with the same device number, we create new block device
inode. However there may be file system device inodes whose i_bdev still
points to the original block device inode and thus we get two active
block device inodes for the same device. They will share the same
gendisk so the only visible differences will be that page caches will
not be coherent and BDIs will be different (the old block device inode
still points to unregistered BDI).
Fix the problem by checking in bd_acquire() whether i_bdev still points
to active block device inode and re-lookup the block device if not. That
way any open of a block device happening after the old device has been
removed will get correct block device inode.

Iteration over partitions in del_gendisk() omits part0. Add
bdev_unhash_inode() call for the whole device. Otherwise if the device
number gets reused, bdev inode will be still associated with the old

Move bdev_unhash_inode() after invalidate_partition() as
invalidate_partition() looks up bdev and it cannot find the right bdev
inode after bdev_unhash_inode() is called. Thus invalidate_partition()
would not invalidate page cache of the previously used bdev. Also use
part_devt() when calling bdev_unhash_inode() instead of manually
creating the device number.

We noticed when trying to do O_DIRECT to an export on the server side
that we were getting requests smaller than the 4k sectorsize of the

setting the queue blocksizes and then calling bd_set_size.

Merge tag 'for-4.11/linus-merge-signed' of git://git.kernel.dk/linux-block
Pull block layer updates from Jens Axboe:
- 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.

removed the inclusion of asm/paravirt.h which is used to get
declarations of paravirt_steal_rq_enabled and paravirt_steal_clock.
It is implicitly included on x86 but not on arm and arm64 breaking the

used directly fix the build by putting the direct inclusion back.

I've also got a few patches, three of which fix bugs related to

journal space:
3. The first one prevents GFS2 delete operation from requesting too
much journal space.
4. The second one fixes a problem whereby GFS2 can hang because it
wasn't taking journal space demand into its calculations.
5. The third one wakes up IO waiters when a flush is done to restart
processes stuck waiting for journal space to become available.
The other three patches are a performance improvement related to
spin_lock contention between multiple writers:
6. The "tr_touched" variable was switched to a flag to be more atomic
and eliminate the possibility of some races.
7. Function meta_lo_add was moved inline with its only caller to make
the code more readable and efficient.
8. Contention on the gfs2_log_lock spinlock was greatly reduced by
avoiding the lock altogether in cases where we don't really need
it: buffers that already appear in the appropriate metadata list
for the journal. Many thanks to Steve Whitehouse for the ideas and
principles behind these patches.

Pull power management updates from Rafael Wysocki:
"The majority of changes go into the Operating Performance Points (OPP)
framework and cpufreq this time, followed by devfreq and some
scattered updates all over.
The OPP changes are mostly related to switching over from RCU-based
synchronization, that turned out to be overly complicated and
problematic, to reference counting using krefs.
In the cpufreq land there are core cleanups, documentation updates, a
new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI
SoCs that require special handling, ARM64 SoCs support for the qoriq
driver, intel_pstate updates, powernv driver update and assorted
fixes.
The devfreq changes are mostly fixes related to the sysfs interface
and some Exynos drivers updates.
Apart from that, the cpuidle menu governor will support per-CPU PM QoS
constraints for the wakeup latency now, some bugs in the wakeup IRQs
framework are fixed, the generic power domains framework should handle
asynchronous invocations of *noirq suspend/resume callbacks from now
on, the analyze_suspend.py script is updated and there is a new tool
for intel_pstate diagnostics.

Pull LED updates from Jacek Anaszewski:
"New features and improvements:
- add new optional brightness_hw_changed attribute for the LEDs that
may have their brightness level changed autonomously (outside of
kernel control) by hardware / firmware. The attribute supports
userspace notifications through POLLPRI events
- add led_brightness_hw_mon tool that demonstrates how to use the
aforementioned feature
- add LED_ON enum for LEDs that can be only turned on/off, and don't
allow setting other brightness levels
- allow for adjusting heartbeat trigger blink brightness level
Fixes and cleanups:
- avoid harmless maybe-uninitialized warning in leds-ktd2692.c
- add context to the existing example entries in common LED bindings
to make the documentation more clear"

Pull perf updates from Ingo Molnar:
"On the kernel side the main changes in this cycle were:
- Add Intel Kaby Lake CPU support (Srinivas Pandruvada)
- AMD uncore driver updates for fam17 (Janakarajan Natarajan)
- Intel/PT updates and core events optimizations and cleanups
(Alexander Shishkin)
- cgroups events fixes (David Carrillo-Cisneros)
- kprobes improvements (Masami Hiramatsu)
- ... plus misc fixes and updates.
On the tooling side the main changes were:
- Support clang build in tools/{perf,lib/{bpf,traceevent,api}} with
CC=clang, to, for instance, take advantage of better warnings
(Arnaldo Carvalho de Melo):
- Introduce the 'delta-abs' 'perf diff' compute method, that orders
the histogram entries by the absolute value of the percentage delta
for a function in two perf.data files, i.e. the functions that
changed the most (increase or decrease in samples) comes first
(Namhyung Kim)
- Add support for parsing Intel uncore vendor event files and add
uncore vendor events for the Intel server processors (Haswell,
Broadwell, IvyBridge), Xeon Phi (Knights Landing) and Broadwell DE
(Andi Kleen)
- Introduce 'perf ftrace' a perf front end to the kernel's ftrace
function and function_graph tracer, defaulting to the
"function_graph" tracer, more work will be done in reviving this
effort, forward porting it from its initial patch submission
(Namhyung Kim)
- Add 'e' and 'c' hotkeys to expand/collapse call chains for a single
hist entry in the 'perf report' and 'perf top' TUI (Jiri Olsa)
- Account thread wait time (off CPU time) separately: sleep, iowait
and preempt, based on the prev_state of the last event, show the
breakdown when using "perf sched timehist --state" (Namhyumg Kim)
- Add more triggers to switch the output file (perf.data.TIMESTAMP).
Now, in addition to switching to a different output file when
receiving a SIGUSR2, one can also specify file size and time based
triggers:
perf record -a --switch-output=signal
is equivalent to what we had before:
perf record -a --switch-output
While we can also ask for the file to be "sliced" by size, taking
into account that that will happen only when we get woken up by the
kernel, i.e. one has to take into account the --mmap-pages (the
size of the perf mmap ring buffer):
perf record -a --switch-output=2G
will break the perf.data output into multiple files limited to 2GB
of samples, right when generating the output.
For time based samples, alert() will be used, so to have 1 minute
limited perf.data output files:
perf record -a --switch-output=1m
(Jiri Olsa)
- Improve 'perf trace' (Arnaldo Carvalho de Melo)
- 'perf kallsyms' toy tool to look for extended symbol information on
the running kernel and demonstrate the machine/thread/symbol APIs
for use in other tools, such as 'perf probe' (Arnaldo Carvalho de
Melo)
- ... plus tons of other changes, see the shortlog and Git log for
details"
