dm-cache's smq policy tries hard to do it's work during the idle periods
when there is no IO. But if there are no idle periods (eg, a long fio
run) we still need to allow some demotions and promotions to occur.
To achieve this, pass @idle=true to queue_promotion()'s
free_target_met() call so that free_target_met() doesn't short-circuit
the possibility of demotion simply because it isn't an idle period.

The WDIOC_SETOPTIONS case in the watchdog ioctl would alwayss falls

The issue is that the internal counter that triggers the watchdog reset
is actually running at 4096 Hz instead of 1Hz, therefore the value
given by userland (in sec) needs to be multiplied by 4096 to get the
correct behavior.

Currently the exclusive lock is acquired only if the mapping is
writable, i.e. an image HEAD mapped in rw mode. This means that we
don't acquire the lock for executing a read from a snapshot or an image
HEAD mapped in ro mode, even if lock_on_read is set. This is somewhat
weird and inconsistent with "no automatic exclusive lock transfers"
mode, where the lock is acquired unconditionally.

add_disk() takes an extra reference on disk->queue, which is put in
put_disk() -> disk_release(). Avoiding blk_cleanup_queue() (which also
puts the queue) until add_disk() sets GENHD_FL_UP works for the queue
itself, but leaks various queue internals. Conditioning tag_set freeing
on GENHD_FL_UP is wrong too: all error paths after rbd_init_disk() leak
the tag_set.
Move the final "announce" steps out of rbd_dev_device_setup() so that
it can be unwound like any other function. Leave "announce" steps to
do_rbd_add/remove().

In page_same_filled function, all elements in the page is compared with
next index value. The current comparison routine compares the (i)th and
(i+1)th values of the page.
In this case, two load operaions occur for each comparison. But if we
store first value of the page stores at 'val' variable and using it to
compare with others, the load opearation is reduced. It reduce load
operation per page by up to 64times.

This patch (of 6):
Johannes Thumshirn reported system goes the panic when using NVMe over
Fabrics loopback target with zram.
The reason is zram expects each bvec in bio contains a single page
but nvme can attach a huge bulk of pages attached to the bio's bvec
so that zram's index arithmetic could be wrong so that out-of-bound
access makes system panic.
[1] in mainline solved solved the problem by limiting max_sectors with
SECTORS_PER_PAGE but it makes zram slow because bio should split with
each pages so this patch makes zram aware of multiple pages in a bvec
so it could solve without any regression(ie, bio split).

bounds accesses

Tetsuo has reported that sysrq triggered OOM killer will print a
misleading information when no tasks are selected:
sysrq: SysRq : Manual OOM execution
Out of memory: Kill process 4468 ((agetty)) score 0 or sacrifice child
Killed process 4468 ((agetty)) total-vm:43704kB, anon-rss:1760kB, file-rss:0kB, shmem-rss:0kB
sysrq: SysRq : Manual OOM execution
Out of memory: Kill process 4469 (systemd-cgroups) score 0 or sacrifice child
Killed process 4469 (systemd-cgroups) total-vm:10704kB, anon-rss:120kB, file-rss:0kB, shmem-rss:0kB
sysrq: SysRq : Manual OOM execution
sysrq: OOM request ignored because killer is disabled
sysrq: SysRq : Manual OOM execution
sysrq: OOM request ignored because killer is disabled
sysrq: SysRq : Manual OOM execution
sysrq: OOM request ignored because killer is disabled
The real reason is that there are no eligible tasks for the OOM killer
to select but since commit 7c5f64f84483 ("mm: oom: deduplicate victim
selection code for memcg and global oom") the semantic of out_of_memory
has changed without updating moom_callback.
This patch updates moom_callback to tell that no task was eligible which
is the case for both oom killer disabled and no eligible tasks. In
order to help distinguish first case from the second add printk to both
oom_killer_{enable,disable}. This information is useful on its own
because it might help debugging potential memory allocation failures.

Pull rdma updates from Doug Ledford:
"More exchaustive description of primary updates in this release:
- Lots of driver fixes and misc fixes across the board.
- I had to base on a net-next tree because the IPoIB Accelorator
patches needed it.
Unfortunately, it was known to Mellanox that there would need to be
an IPoIB accelorator patch to the net tree (which left some
functions turned off by an #ifdef construct to avoid warnings about
defined but unused functions), then one to the RDMA tree, then a
fixup that went back and re-enabled the functions in the net tree
and enabled their use in the rdma tree
Also, a sparse fix was sent to the net tree after I did my pull,
and the fixup patch conflicts quite directly with that sparse fix,
so I'm going to submit the fixup patch towards the end of the merge
window by itself and based upon your master branch at the time.
- Two separate rounds of hfi1 fixes, one that got dropped from last
release because it came in just a day or two before the end of the
merge window and then the one from this release cycle.
Of note is that I now have a third series that just landed from
Intel yesterday. It is not included in this pull request, but I may
submit it by the end of the week. I'll talk to Intel about
improving the timing of thier submissions for my workflow.
- Changes to our idr usage in the RDMA subsystem that will tie into
our cgroup management and also into the upcoming changes for the
RDMA kernel<->userspace API.
- Addition of support for a netdev to be tied to an RDMA device at
the core level
- Addition of the VNIC driver from Intel.
While IPoIB provides IP over InfiniBand (and *only* IP, no lower
layer protocol headers are allowed or supported), the VNIC driver
presents a virtual Ethernet device with support for things like
varying Ethertypes, VLANs, priorities and other features of
Ethernet.
The virtual devices are centrally managed by the OPA fabric
manager, making this (for the time being) a strictly OPA specific
feature.
- Improvements to the On-Demand Paging support in the RDMA subsystem.
- Addition of three significant OPA changes.
While we added OPA support some time ago (via the hfi1 driver), the
RDMA subsystem has so far glossed over the areas where OPA and
InfiniBand differ.
With this release we are starting to add support for the OPA
extensions into the RDMA core in the following area: Extended port
information for OPA is now supported, extended Address Handle
attributes for OPA are now supported, and extended SA Queries to
get OPA specific subnet information is now supported.
Concise summary from the tag:
- idr usage and locking changes
- build fix for hns
- ipoib debug path record file fix
- hfi1 updates
- core RDMA netdev addition
- Intel VNIC driver addition
- Enhanced accelerators for IPoIB addition
- Debug cleanups in cxgb3/4
- Trivial cleanups from SF Markus Elfring
- Misc rxe fixes from Mellanox
- Misc ipoib fixes from Mellanox
- Lots of mlx4/mlx5 changes from Mellanox
- Misc fixes across the RDMA subsystem
- ODP paging fixes and improvements
- qedr updates

commit 1647b9b9 "brd: add dax_operations support" introduced the allocation
and freeing of a dax_device, but the allocated dax_device is not stored
into the brd_device, so brd_del_one() will eventually operate on an
uninitialized brd->dax_dev.
Fix this by storing the allocated dax_device to brd->dax_dev.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer:
- A major update for DM cache that reduces the latency for deciding
whether blocks should migrate to/from the cache. The bio-prison-v2
interface supports this improvement by enabling direct dispatch of
work to workqueues rather than having to delay the actual work
dispatch to the DM cache core. So the dm-cache policies are much more
nimble by being able to drive IO as they see fit. One immediate
benefit from the improved latency is a cache that should be much more
adaptive to changing workloads.
- Add a new DM integrity target that emulates a block device that has
additional per-sector tags that can be used for storing integrity
information.
- Add a new authenticated encryption feature to the DM crypt target
that builds on the capabilities provided by the DM integrity target.
- Add MD interface for switching the raid4/5/6 journal mode and update
the DM raid target to use it to enable aid4/5/6 journal write-back
support.
- Switch the DM verity target over to using the asynchronous hash
crypto API (this helps work better with architectures that have
access to off-CPU algorithm providers, which should reduce CPU
utilization).
- Various request-based DM and DM multipath fixes and improvements from
Bart and Christoph.
- A DM thinp target fix for a bio structure leak that occurs for each
discard IFF discard passdown is enabled.
- A fix for a possible deadlock in DM bufio and a fix to re-check the
new buffer allocation watermark in the face of competing admin
changes to the 'max_cache_size_bytes' tunable.
- A couple DM core cleanups.
