[GIT PULL] dax fixes for v5.6-rc2

[Dan Williams]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/dax-fixes-5.6-rc1

...to receive a fix for an xfstest failure and some and an update that
removes an fsdax dependency on block devices. The update is small
enough that I held it back to merge with the fix post -rc1 and let it
all appear in a -next release. No reported issues in -next.
