Merge tag 'for-linus-2019-10-26' of git://git.kernel.dk/linux-block
Pull block and io_uring fixes from Jens Axboe:
"A bit bigger than usual at this point in time, mostly due to some good
bug hunting work by Pavel that resulted in three io_uring fixes from
him and two from me. Anyway, this pull request contains:
- Revert of the submit-and-wait optimization for io_uring, it can't
always be done safely. It depends on commands always making
progress on their own, which isn't necessarily the case outside of
strict file IO. (me)
- Series of two patches from me and three from Pavel, fixing issues
with shared data and sequencing for io_uring.
- Lastly, two timeout sequence fixes for io_uring (zhangyi)
- Two nbd patches fixing races (Josef)
- libahci regulator_get_optional() fix (Mark)"

nbd requires socket families to support the shutdown method so the nbd
recv workqueue can be woken up from its sock_recvmsg call. If the socket
does not support the callout we will leave recv works running or get hangs
later when the device or module is removed.
This adds a check during socket connection/reconnection to make sure the
socket being passed in supports the needed callout.

This driver is using regulator_get_optional() to handle all the supplies
that it handles, and only ever enables and disables all supplies en masse
without ever doing any other configuration of the device to handle missing
power. These are clear signs that the API is being misused - it should only
be used for supplies that may be physically absent from the system and in
these cases the hardware usually needs different configuration if the
supply is missing. Instead use normal regualtor_get(), if the supply is
not described in DT then the framework will substitute a dummy regulator in
so no special handling is needed by the consumer driver.
In the case of the PHY regulator the handling in the driver is a hack to
deal with integrated PHYs; the supplies are only optional in the sense
that that there's some confusion in the code about where they're bound to.
From a code point of view they function exactly as normal supplies so can
be treated as such. It'd probably be better to model this by instantiating
a PHY object for integrated PHYs.

This was preceded by us timing out everything and shutting down the
sockets for the device. The problem is we had a request in the queue at
the same time, so we completed the request twice. This can actually
happen in a lot of cases, we fail to get a ref on our config, we only
have one connection and just error out the command, etc.
Fix this by checking cmd->status in nbd_read_stat. We only change this
under the cmd->lock, so we are safe to check this here and see if we've
already error'ed this command out, which would indicate that we've
completed it as well.

We already do this for the most part, except in timeout and clear_req.
For the timeout case we take the lock after we grab a ref on the config,
but that isn't really necessary because we're safe to touch the cmd at
this point, so just move the order around.
For the clear_req cause this is initiated by the user, so again is safe.

We currently assume that submissions from the sqthread are successful,
and if IO polling is enabled, we use that value for knowing how many
completions to look for. But if we overflowed the CQ ring or some
requests simply got errored and already completed, they won't be
available for polling.
For the case of IO polling and SQTHREAD usage, look at the pending
poll list. If it ever hits empty then we know that we don't have
anymore pollable requests inflight. For that case, simply reset
the inflight count to zero.

We currently use the ring values directly, but that can lead to issues
if the application is malicious and changes these values on our behalf.
Created in-kernel cached versions of them, and just overwrite the user
side when we update them. This is similar to how we treat the sq/cq
ring tail/head updates.

io_sq_thread() processes sqes by 8 without considering links. As a
result, links will be randomely subdivided.
The easiest way to fix it is to call io_get_sqring() inside
io_submit_sqes() as do io_ring_submit().
Downsides:
1. This removes optimisation of not grabbing mm_struct for fixed files
2. It submitting all sqes in one go, without finer-grained sheduling
with cq processing.

There is a bug, where failed linked requests are returned not with
specified @user_data, but with garbage from a kernel stack.
The reason is that io_fail_links() uses req->user_data, which is
uninitialised when called from io_queue_sqe() on fail path.

Pull power management fixes from Rafael Wysocki:
"These fix problems related to frequency limits management in cpufreq
that were introduced during the 5.3 cycle (when PM QoS had started to
be used for that), fix a few issues in the OPP (operating performance
points) library code and fix up the recently added haltpoll cpuidle
driver.
The cpufreq changes are somewhat bigger that I would like them to be
at this stage of the cycle, but the problems fixed by them include
crashes on boot and shutdown in some cases (among other things) and in
my view it is better to address the root of the issue right away.

cpufreq does not work, so introduce frequency QoS (based on the

gfs2 and gfs2meta share an ->init_fs_context function which allocates an
args structure stored in fc->fs_private. gfs2 registers a ->free
function to free this memory when the fs_context is cleaned up, but
there was not one registered for gfs2meta, causing a leak.
Register a ->free function for gfs2meta. The existing gfs2_fc_free
function does what we need.

The sequence number of the timeout req (req->sequence) indicate the
expected completion request. Because of each timeout req consume a
sequence number, so the sequence of each timeout req on the timeout
list shouldn't be the same. But now, we may get the same number (also
incorrect) if we insert a new entry before the last one, such as submit
such two timeout reqs on a new ring instance below.
req->sequence
req_1 (count = 2): 2
req_2 (count = 1): 2
Then, if we submit a nop req, req_2 will still timeout even the nop req
finished. This patch fix this problem by adjust the sequence number of
each reordered reqs when inserting a new entry.

The sequence number of reqs on the timeout_list before the timeout req
should be adjusted in io_timeout_fn(), because the current timeout req
will consumes a slot in the cq_ring and cq_tail pointer will be
increased, otherwise other timeout reqs may return in advance without
waiting for enough wait_nr.

There are cases where it isn't always safe to block for submission,
even if the caller asked to wait for events as well. Revert the
previous optimization of doing that.
This reverts two commits:

Commit d698a388146c ("of: reserved-memory: ignore disabled memory-region

didn't call of_node_put() on a device_node whose ref-count was incremented
in the call to of_parse_phandle() preceding the early exit.

There are a few core fixes here around error handling and handling if
suspend mode configuration and some driver specific fixes here but the
most important change is the fix to the fixed-regulator DT schema
conversion introduced during the last merge window. That fixes one of
the last two errors preventing successful execution of "make dt_binding_check"
which will be enourmously helpful for DT schema development.
