This patchset is to add gracefully unbind support for pmem.
Patch1 corrects the calculation of length and end of a given range.
Patch2 introduces a new flag call MF_MEM_REMOVE, to let dax holder know
it is a remove event. With the help of notify_failure mechanism, we are
able to shutdown the filesystem on the pmem gracefully.
What is the status of this patch?

Thanks,

Thanks-

Changes since v11:
Patch1:
1. correct the count calculation in xfs_failure_pgcnt().
(was a wrong fix in v11)
Patch2:
1. use new exclusive freeze_super/thaw_super API, to make sure the unbind
progress won't be disturbed by any other freezer.
Shiyang Ruan (2):
xfs: fix the calculation for "end" and "length"
mm, pmem, xfs: Introduce MF_MEM_REMOVE for unbind
