Subject: [PATCH 0/2] fix regression in direct I/O to pmem devices

Linda Knippers noticed that commit bbab37ddc20b (block: Add support
for DAX reads/writes to block devices) caused a regression in mkfs.xfs.
Further investigation also uncovered issues related to misaligned
partitions.  This patch set addresses the two issues.

[PATCH 1/2] dax: fix O_DIRECT I/O to the last block of a blockdev
[PATCH 2/2] blockdev: don't set S_DAX for misaligned partitions
