Pull MD updates from Shaohua Li:
- a raid5 writeback cache feature.
The goal is to aggregate writes to make full stripe write and reduce
read-modify-write. It's helpful for workload which does sequential
write and follows fsync for example. This feature is experimental and
off by default right now.
- FAILFAST support.
This fails IOs to broken raid disks quickly, so can improve latency.
It's mainly for DASD storage, but some patches help normal raid array
too.
- support bad block for raid array with external metadata
- AVX2 instruction support for raid6 parity calculation
- normalize MD info output
- add missing blktrace
- other bug fixes

Resetting audit_sock appears to be racy.
audit_sock was being copied and dereferenced without using a refcount on
the source sock.
Bump the refcount on the underlying sock when we store a refrence in
audit_sock and release it when we reset audit_sock. audit_sock
modification needs the audit_cmd_mutex.
See: https://lkml.org/lkml/2016/11/26/232

Sleeping on a command record/message in audit_log_start() could slow
something, e.g. auditd, from doing something important, e.g. clean
shutdown, which could present problems on a heavily loaded system.
This patch allows tasks to bypass any queue restrictions if they are
logging a command record/message.

When auditd stops cleanly it sets 'auditd_pid' to 0 with an
AUDIT_SET message, in this case we should reset our backlog
queues via the auditd_reset() function. This patch also adds
a 'auditd_pid' check to the top of kauditd_send_unicast_skb()
so we can fail quicker.

The backlog queue handling in audit_log_start() is a little odd with
some questionable design decisions, this patch attempts to rectify
this with the following changes:
* Never make auditd wait, ignore any backlog limits as we need auditd
awake so it can drain the backlog queue.
* When we hit a backlog limit and start dropping records, don't wake
all the tasks sleeping on the backlog, that's silly. Instead, let
kauditd_thread() take care of waking everyone once it has had a chance
to drain the backlog queue.
* Don't keep a global backlog timeout countdown, make it per-task. A
per-task timer means we won't have all the sleeping tasks waking at
the same time and hammering on an already stressed backlog queue.

The audit record backlog queue has always been a bit of a mess, and
the moving the multicast send into kauditd_thread() from
audit_log_end() only makes things worse. This patch attempts to fix
the backlog queue with a better design that should hold up better
under load and have less of a performance impact at syscall
invocation time.
While it looks like there is a log going on in this patch, the main
change is the move from a single backlog queue to three queues:
* A queue for holding records generated from audit_log_end() that
haven't been consumed by kauditd_thread() (audit_queue).
* A queue for holding records that have been sent via multicast but
had a temporary failure when sending via unicast and need a resend
(audit_retry_queue).
* A queue for holding records that haven't been sent via unicast
because no one is listening (audit_hold_queue).
Special care is taken in this patch to ensure that the proper
record ordering is preserved, e.g. we send everything in the hold
queue first, then the retry queue, and finally the main queue.

The audit queue names can be shortened and the record sending
helpers associated with the kauditd task could be named better, do
these small cleanups now to make life easier once we start reworking
the queues and kauditd code.

Sending audit netlink multicast messages is bad for all the same
reasons that sending audit netlink unicast messages is bad, so this
patch reworks things so that we don't do the multicast send in
audit_log_end(), we do it from the dedicated kauditd_thread thread just
as we do for unicast messages.

Richard made this change some time ago but Eric backed it out because
the rest of the supporting code wasn't ready. In order to move the
netlink multicast send to kauditd_thread we need to ensure the
kauditd_thread is always running, so restore commit 6ff5e459 ("audit:
move kaudit thread start from auditd registration to kaudit init").

While stressing memory and IO at the same time we changed SMT settings,
we were able to consistently trigger deadlocks in the mm system, which
froze the entire machine.
I think that under memory stress conditions, the large allocations
performed by blk_mq_init_rq_map may trigger a reclaim, which stalls
waiting on the block layer remmaping completion, thus deadlocking the
system. The trace below was collected after the machine stalled,
waiting for the hotplug event completion.
The simplest fix for this is to make allocations in this path
non-reclaimable, with GFP_NOIO. With this patch, We couldn't hit the
issue anymore.
This should apply on top of Jens's for-next branch cleanly.
Changes since v1:
- Use GFP_NOIO instead of GFP_NOWAIT.

Commit 4fd06960f120 ("Use the new x86 setup code for i386") introduced a
reference to the make variable LINUX_INCLUDE. That reference got moved
around a bit and copied twice and now there are three references to it.
There has never been a definition of that variable. (Presumably that is
because it started out as a mistyped reference to LINUXINCLUDE.) So this
reference has always been an empty string. Let's remove it before it

When debugging nvme controller crashes, it's nice to know whether
the controller died cleanly so that the failure is just reflected in
CSTS, it died and put an error in PCI_STATUS, or whether it died so
badly that it stopped responding to PCI configuration space reads.
I've seen a failure that gives 0xffff in PCI_STATUS on a Samsung
"SM951 NVMe SAMSUNG 256GB" with firmware "BXW75D0Q".

bdev->bd_contains is not stable before calling __blkdev_get().
When __blkdev_get() is called on a parition with ->bd_openers == 0
it sets
bdev->bd_contains = bdev;
which is not correct for a partition.
After a call to __blkdev_get() succeeds, ->bd_openers will be > 0
and then ->bd_contains is stable.
When FMODE_EXCL is used, blkdev_get() calls
bd_start_claiming() -> bd_prepare_to_claim() -> bd_may_claim()
This call happens before __blkdev_get() is called, so ->bd_contains
is not stable. So bd_may_claim() cannot safely use ->bd_contains.
It currently tries to use it, and this can lead to a BUG_ON().
This happens when a whole device is already open with a bd_holder (in
use by dm in my particular example) and two threads race to open a
partition of that device for the first time, one opening with O_EXCL and
one without.
The thread that doesn't use O_EXCL gets through blkdev_get() to
__blkdev_get(), gains the ->bd_mutex, and sets bdev->bd_contains = bdev;
Immediately thereafter the other thread, using FMODE_EXCL, calls
bd_start_claiming() from blkdev_get(). This should fail because the
whole device has a holder, but because bdev->bd_contains == bdev
bd_may_claim() incorrectly reports success.
This thread continues and blocks on bd_mutex.
The first thread then sets bdev->bd_contains correctly and drops the mutex.
The thread using FMODE_EXCL then continues and when it calls bd_may_claim()
again in:
BUG_ON(!bd_may_claim(bdev, whole, holder));
The BUG_ON fires.
Fix this by removing the dependency on ->bd_contains in
bd_may_claim(). As bd_may_claim() has direct access to the whole
device, it can simply test if the target bdev is the whole device.

This reverts commit 6d31e3ba232ea22458b2f36b6d3f2f9f11bf3fa4.
This causes bootup problems for me both on my laptop and my desktop.
What they have in common is that they have NVMe disks with dm-crypt, but
it's not the same controller, so it's not controller-specific.
Jens does not see it on his machine (also NVMe), so it's presumably
something that triggers just on bootup. Possibly related to dm-crypt
and the fact that I mark my luks volume with "allow-discards" in
/etc/crypttab.
It's 100% repeatable for me, which made it fairly straightforward to
bisect the problem to this commit. Small mercies.
So we don't know what the reason is yet, but the revert is needed to get
things going again.

Pull another libata patch from Tejun Heo:
"One more patch from Adam added.
It makes libata skip probing for NCQ prio unless the feature is

ata: avoid probing NCQ Prio Support if not explicitly requested
|
|
Previously, when the ata device was being initialized we were
probing for NCQ prio support by checking the identify information
and also checking the log page that holds information about ncq prio
support.
This caused an error on an Intel HBA so the code is now updated to
only probe for NCQ prio support when the sysfs variable controlling
NCQ prio support is enabled.
tj: Update formatting, switch to spin_[un]lock_irq() and update
locking a bit, use REVALIDATE instead of RESET, and return -EIO
instead of -EINVAL on config failure.

"I wish that was the case. We've pretty much agreed that we'll want to
implement it as a virtual PCIe root bridge, similar to Intels other
'innovation' VMD that we work around that way.
But Intel management has apparently decided that they don't want to
spend more cycles on this now that Lenovo has an optional BIOS that
doesn't force this broken mode anymore, and no one outside of Intel
has enough information to implement something like this.
So for now I guess this warning is it, until Intel reconsideres and
