Pull more block updates from Jens Axboe:
"A later pull request with some followup items. I had some vacation
coming up to the merge window, so certain things items were delayed a
bit. This pull request also contains fixes that came in within the
last few days of the merge window, which I didn't want to push right
before sending you a pull request.
This contains:
- NVMe pull request, mostly fixes, but also a few minor items on the
feature side that were timing constrained (Christoph et al)
- Report zones fixes (Damien)
- Removal of dead code (Damien)
- Turn on cgroup psi memstall (Josef)
- block cgroup MAINTAINERS entry (Konstantin)

A previous commit changed the prototype, but didn't adjust the function
for when zoned device support is disabled. Fix it up.

Only GFP_KERNEL and GFP_NOIO are used with blkdev_report_zones(). In
preparation of using vmalloc() for large report buffer and zone array
allocations used by this function, remove its "gfp_t gfp_mask" argument
and rely on the caller context to use memalloc_noio_save/restore() where
necessary (block layer zone revalidation and dm-zoned I/O error path).

If the device is setup with ioctl we can resize the device after the
initial setup, but if the device is setup with netlink we cannot use the
resize related ioctls and there is no netlink reconfigure size ATTR
handling code.
This patch adds netlink reconfigure resize support to match the ioctl
interface.

Pull Documentation updates from Jonathan Corbet:
"It's been a relatively busy cycle for docs:
- A fair pile of RST conversions, many from Mauro. These create more
than the usual number of simple but annoying merge conflicts with
other trees, unfortunately. He has a lot more of these waiting on
the wings that, I think, will go to you directly later on.
- A new document on how to use merges and rebases in kernel repos,
and one on Spectre vulnerabilities.
- Various improvements to the build system, including automatic
markup of function() references because some people, for reasons I
will never understand, were of the opinion that
:c:func:``function()`` is unattractive and not fun to type.
- We now recommend using sphinx 1.7, but still support back to 1.4.
- Lots of smaller improvements, warning fixes, typo fixes, etc"

The stuff there is almost already at ReST format. A
conversion for them is trivial: just add a missing titles
and fix some scape codes for them to match ReST syntax.
While here, rename the cdrom-standard.txt, with was converted
from LaTeX to ReST on the previous patch, and add it to the
index file.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Merge 5.2-rc6 into for-5.3/block, so we get the same page merge leak
fix. Otherwise we end up having conflicts with future patches between
for-5.3/block and master that touch this area. In particular, it makes
the bio_full() fix hard to backport to stable.

If we pass pages through an iov_iter we always already have a reference
in the caller. Thus remove the ITER_BVEC_FLAG_NO_REF and don't take
reference to pages by default for bvec backed iov_iters.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

In function null_add_dev() struct nullb *nullb member is allocated
using kzalloc_node() which returns 0red memory.
In function setup_queues() which is called from the null_add_dev(), on
successful queue allocation we set the nullb->nr_queues = 0 which is not
needed due to earlier use of kzalloc_node().

clang warns about unusual code in floppy.c that looks like it
was intended to be a bit mask operation, checking for a specific
bit in the UDP->cmos variable (FLOPPY1_TYPE expands to '4' on
ARM):
drivers/block/floppy.c:3902:17: error: use of logical '&&' with constant operand [-Werror,-Wconstant-logical-operand]
if (!UDP->cmos && FLOPPY1_TYPE)
^ ~~~~~~~~~~~~
drivers/block/floppy.c:3902:17: note: use '&' for a bitwise operation
if (!UDP->cmos && FLOPPY1_TYPE)
The check here is redundant anyway, if FLOPPY1_TYPE is zero, then
assigning it to a zero UDP->cmos field does not change anything,
so removing the extra check here has no effect other than shutting
up the warning.
On x86, this will no longer read a hardware register, as the
FLOPPY1_TYPE macro is not expanded if UDP->cmos is already
zero, but the result is the same.

Dulicate call of null_del_dev() will trigger null pointer error like below.
The reason is a race condition between nullb_device_power_store() and
nullb_group_drop_item().

---------------- -----------------
do_rmdir()
>configfs_rmdir()
>client_drop_item()
>nullb_group_drop_item()

>test_and_clear_bit(NULLB_DEV_FL_UP
>null_del_dev()
^^^^^
Duplicated null_dev_dev() triger null pointer error
>clear_bit(NULLB_DEV_FL_UP
The fix could be keep the sequnce of clear NULLB_DEV_FL_UP and null_del_dev().

Pull force_sig() argument change from Eric Biederman:
"A source of error over the years has been that force_sig has taken a
task parameter when it is only safe to use force_sig with the current
task.
The force_sig function is built for delivering synchronous signals
such as SIGSEGV where the userspace application caused a synchronous
fault (such as a page fault) and the kernel responded with a signal.
Because the name force_sig does not make this clear, and because the
force_sig takes a task parameter the function force_sig has been
abused for sending other kinds of signals over the years. Slowly those
have been fixed when the oopses have been tracked down.
This set of changes fixes the remaining abusers of force_sig and
carefully rips out the task parameter from force_sig and friends
making this kind of error almost impossible in the future"

The drbd module exclusively sends signals to kernel threads it creates with
kthread_create. These kernel threads do not block or ignore signals (only
flush signals after they have been delivered), nor can drbd threads
possibly be pid namespace init processes so the extra work that force_sig
performs that send_sig does not is unnecessary.
Further force_sig is for delivering synchronous signals (aka exceptions).
The locking in force_sig is not prepared to deal with running processes, as
tsk->sighand may change during exec for a running process.
In short it is not only unnecessary for drbd to use force_sig it is
semantically wrong.
With drbd using send_sig it becomes easier to maintain force_sig as only
synchronous signals need to be considered.

The removal of CONFIG_LBDAF changed the type of sector_t from "unsigned
long" to "u64" aka "unsigned long long" on 64-bit platforms, leading to
a compiler warning regression:
drivers/block/ps3vram.c: In function ‘ps3vram_probe’:
drivers/block/ps3vram.c:770:23: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘sector_t {aka long long unsigned int}’ [-Wformat=]
Fix this by using "%llu" instead.

This patch removes the check in the null_blk_zoned for report zone
command, where it checks for the dev-,>zoned before executing the report
zone.
The null_zone_report() function is a block_device operation callback
which is initialized in the null_blk_main.c and gets called as a part
of blkdev for report zone IOCTL (BLKREPORTZONE).
blkdev_ioctl()
blkdev_report_zones_ioctl()
blkdev_report_zones()
blk_report_zones()
disk->fops->report_zones()
nullb_zone_report();
The null_zone_report() will never get executed on the non-zoned block
device, in the non zoned block device blk_queue_is_zoned() will always
be false which is first check the blkdev_report_zones_ioctl()
before actual low level driver report zone callback is executed.
Here is the detailed scenario:-
1. modprobe null_blk
null_init
null_alloc_dev
dev->zoned = 0
null_add_dev
dev->zoned == 0
so we don't set the q->limits.zoned = BLK_ZONED_HR
2. blkzone report /dev/nullb0
blkdev_ioctl()
blkdev_report_zones_ioctl()
blk_queue_is_zoned()
blk_queue_is_zoned
q->limits.zoned == 0
return false
if (!blk_queue_is_zoned(q)) <--- true
return -ENOTTY;

Loop module allows calling LOOP_SET_FD while there are other openers of
the loop device. Even exclusive ones. This can lead to weird
consequences such as kernel deadlocks like:
mount_bdev() lo_ioctl()
udf_fill_super()
udf_load_vrs()
sb_set_blocksize() - sets desired block size B
udf_tread()
sb_bread()
__bread_gfp(bdev, block, B)
loop_set_fd()
set_blocksize()
- now __getblk_slow() indefinitely loops because B != bdev
block size
Fix the problem by disallowing LOOP_SET_FD ioctl when there are
exclusive openers of a loop device.
[Deliberately chosen not to CC stable as a user with priviledges to
trigger this race has other means of taking the system down and this
has a potential of breaking some weird userspace setup]

"On the filesystem side we have:
- a fix to enforce quotas set above the mount point (Luis Henriques)
- support for exporting snapshots through NFS (Zheng Yan)
- proper statx implementation (Jeff Layton). statx flags are mapped
to MDS caps, with AT_STATX_{DONT,FORCE}_SYNC taken into account.
- some follow-up dentry name handling fixes, in particular
elimination of our hand-rolled helper and the switch to __getname()
as suggested by Al (Jeff Layton)
- a set of MDS client cleanups in preparation for async MDS requests
in the future (Jeff Layton)
- a fix to sync the filesystem before remounting (Jeff Layton)

The check added in commit 721c7fc701c7 ("block: fail op_is_write()
requests to read-only partitions") was lifted in commit a32e236eb93e
("Partially revert "block: fail op_is_write() requests to read-only
partitions""). Basic things like user triggered writes and discards
are still caught, but internal kernel users can submit anything. In
particular, ext4 will attempt to write to the superblock if it detects
errors in the filesystem, even if the filesystem is mounted read-only
on a read-only partition.
The assert is overkill regardless.

rbd_assert(0) has caused different issues depending on
the compiler version in the past, so it seems better to avoid it
completely.
Replace the remaining instances.

This seems to be a bug in clang, but is easy to work around by using
an unconditional BUG().
