Subject[GIT PULL] libnvdimm / persistent memory update for v5.15
Hi Linus, please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-for-5.15

...to receive the libnvdimm update for v5.15. It includes a bug fix
for a long standing race in the driver shutdown path. More people are
stress testing the nvdimm configuration mechanism which is a welcome
sign. There is also a rework of the infrastructure for looking up the
dax_device associated with a block_device.

This collided (silent conflict) with the erofs updates to add dax
support this cycle. Gao Xiang noted this as well in the erofs pull
request. Stephen's fix [1] looked correct to me. Otherwise, it has
been in -next for a while with no other reported issues.

Please pull, thanks,
Dan
