Subject: [PATCH 0/3] Add alignment check for DAX mount
Date: Fri, 29 Apr 2016 14:39:32 -0600	[thread overview]
Message-ID: <1461962375-3720-1-git-send-email-toshi.kani@hpe.com> (raw)

When a partition is not aligned by 4KB, mount -o dax succeeds,
but any read/write access to the filesystem fails, except for
metadata update.

Add alignment check to ext4, ext2, and xfs.
