Pull device mapper fixes from Mike Snitzer:
- Fix dm core to use more efficient bio_split() instead of
bio_clone_bioset(). Also fixes splitting bio that has integrity
payload.
- Three fixes related to properly validating DAX capabilities of a
stacked DM device that will advertise DAX support.
- Update DM writecache target to use 2-factor allocator arguments. Kees
says this is the last related change for 4.18.
- Fix DM zoned target to use GFP_NOIO to avoid triggering reclaim
during IO submission (caught by lockdep).
- Fix DM thinp to gracefully recover from running out of data space
while a previous async discard completes (whereby freeing space).
- Fix DM thinp's metadata transaction commit to avoid needless work.

io_pgetevents() will not change the signal mask. Mark it const to make

This reverts commit 3e5f06bed7. As per
bugzilla #200045, this caused a regression. I don't really see a way to
fix it without having the hardware. So, revert the patch and I will fix
the issue I was seeing originally in the i2c-gpio driver itself. I
couldn't find new users of this algorithm since, so there should be no
one depending on the new behaviour.

Currently device_supports_dax() just checks to see if the QUEUE_FLAG_DAX
flag is set on the device's request queue to decide whether or not the
device supports filesystem DAX. Really we should be using
bdev_dax_supported() like filesystems do at mount time. This performs
other tests like checking to make sure the dax_direct_access() path works.
We also explicitly clear QUEUE_FLAG_DAX on the DM device's request queue if
any of the underlying devices do not support DAX. This makes the handling
of QUEUE_FLAG_DAX consistent with the setting/clearing of most other flags
in dm_table_set_restrictions().
Now that bdev_dax_supported() explicitly checks for QUEUE_FLAG_DAX, this
will ensure that filesystems built upon DM devices will only be able to
mount with DAX if all underlying devices also support DAX.

Add an explicit check for QUEUE_FLAG_DAX to __bdev_dax_supported(). This
is needed for DM configurations where the first element in the dm-linear or
dm-stripe target supports DAX, but other elements do not. Without this
check __bdev_dax_supported() will pass for such devices, letting a
filesystem on that device mount with the DAX option.

QUEUE_FLAG_DAX is an indication that a given block device supports
filesystem DAX and should not be set for PMEM namespaces which are in "raw"
mode. These namespaces lack struct page and are prevented from
participating in filesystem DAX as of commit 569d0365f5 ("dax: require
'struct page' by default for filesystem dax").
