Subject: [GIT PULL] LIBNVDIMM and DAX for 5.19
Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-for-5.19
...to receive new support for clearing memory errors when a file is in
DAX mode, alongside with some other fixes and cleanups. Previously it
was only possible to clear these errors using a truncate or hole-punch
operation to trigger the filesystem to reallocate the block, now, any
page aligned write can opportunistically clear errors as well. This
change spans x86/mm, nvdimm, and fs/dax, and has received the
appropriate sign-offs. Thanks to Jane for her work on this. It has
been in -next for several releases with no known remaining issues.
