3d966521a8 exfat: fix missing REQ_SYNC in exfat_update_bhs() 
If 'dirsync' is enabled, all directory updates within the
filesystem should be done synchronously. exfat_update_bh()
does as this, but exfat_update_bhs() does not.

92fba084b7 exfat: fix i_blocks for files truncated over 4 GiB 
In exfat_truncate(), the computation of inode->i_blocks is wrong if
the file is larger than 4 GiB because a 32-bit variable is used as a
mask. This is fixed and simplified by using round_up().

Also fix the same buggy computation in exfat_read_root() and another
(correct) one in exfat_fill_inode(). The latter was fixed another way
last month but can be simplified by using round_up() as well. See:

  commit 0c336d6e33 ("exfat: fix incorrect loading of i_blocks for
                        large files")

849ab826e1 docs: sysfs-block: fill in missing documentation from queue-sysfs.rst 
sysfs documentation is supposed to go in Documentation/ABI/.
However, /sys/block/<disk>/queue/* are documented in
Documentation/block/queue-sysfs.rst, and sometimes redundantly in
Documentation/ABI/stable/sysfs-block too.

Let's consolidate this documentation into Documentation/ABI/.

Therefore, copy the relevant docs from queue-sysfs.rst into sysfs-block.

This primarily means adding the 25 missing files that were documented in
queue-sysfs.rst only, as well as mentioning the RO/RW status of files.

Documentation/ABI/ requires "Date" and "Contact" fields.  For the Date
fields, I used the date of the commit which added support for each file.
For the "Contact" fields, I used linux-block.

07c9093c42 docs: sysfs-block: sort alphabetically 
Sort the documentation for the files alphabetically by file path so that
there is a logical order and it's clear where to add new files.

With two small exceptions, this patch doesn't change the documentation
itself and just reorders it:

- In /sys/block/<disk>/<part>/stat, I replaced <part> with <partition>
  to be consistent with the other files.
- The description for /sys/block/<disk>/<part>/stat referred to another
  file "above", which I reworded.

9d497e2941 block: don't protect submit_bio_checks by q_usage_counter 
Commit cc9c884dd7 ("block: call submit_bio_checks under q_usage_counter")
uses q_usage_counter to protect submit_bio_checks for avoiding IO after
disk is deleted by del_gendisk().

Turns out the protection isn't necessary, because once
blk_mq_freeze_queue_wait() in del_gendisk() returns:

1) all in-flight IO has been done

2) all new IO will be failed in __bio_queue_enter() because
   q_usage_counter is dead, and GD_DEAD is set

3) both disk and request queue instance are safe since caller of
submit_bio() guarantees that the disk can't be closed.

Once submit_bio_checks() needn't the protection of q_usage_counter, we can
move submit_bio_checks before calling blk_mq_submit_bio() and
->submit_bio(). With this change, we needn't to throttle queue with
holding one allocated request, then precise driver tag or request won't be
wasted in throttling. Meantime we can unify the bio check for both bio
based and request based driver.

With 'unevaluatedProperties' support implemented, the properties

Documentation/devicetree/bindings/net/intel,dwmac-plat.example.dt.yaml: ethernet@3a000000: Unevaluated properties are not allowed ('snps,pbl', 'mdio0' were unexpected)
Documentation/devicetree/bindings/net/stm32-dwmac.example.dt.yaml: ethernet@5800a000: Unevaluated properties are not allowed ('reg-names', 'snps,pbl' were unexpected)
Documentation/devicetree/bindings/net/stm32-dwmac.example.dt.yaml: ethernet@40028000: Unevaluated properties are not allowed ('reg-names', 'snps,pbl' were unexpected)
Documentation/devicetree/bindings/net/stm32-dwmac.example.dt.yaml: ethernet@40027000: Unevaluated properties are not allowed ('reg-names', 'snps,pbl' were unexpected)

This appears to be an oversight, so fix it by allowing the properties
on the v3.50a, v4.10a, and v4.20a versions of the DWMAC.

3cb6ee9914 9p: only copy valid iattrs in 9P2000.L setattr implementation 
The 9P2000.L setattr method v9fs_vfs_setattr_dotl() copies struct iattr
values without checking whether they are valid causing unitialized
values to be copied. The 9P2000 setattr method v9fs_vfs_setattr() method
gets this right. Check whether struct iattr fields are valid first
before copying in v9fs_vfs_setattr_dotl() too and make sure that all
other fields are set to 0 apart from {g,u}id which should be set to
INVALID_{G,U}ID. This ensure that they can be safely sent over the wire
or printed for debugging later on.

0959a82ab3 net/qla3xxx: Remove useless DMA-32 fallback configuration 
As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.

So, if dma_set_mask_and_coherent() succeeds, 'pci_using_dac' is known to be
1.

Simplify code and remove some dead code accordingly.

As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.

Moreover, dma_set_mask_and_coherent() returns 0 or -EIO, so the return
code of the function can be used directly.

Finally, inline bnx2x_set_coherency_mask() because it is now only a wrapper
for a single dma_set_mask_and_coherent() call.

So if dma_set_mask_and_coherent() succeeds, 'netdev->features' will have

be_netdev_init() instead be_probe() which is a much logical place.
