Subject[PATCH 4.14 45/53] dm: set QUEUE_FLAG_DAX accordingly in dm_table_set_restrictions()
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mike Snitzer <snitzer@redhat.com>

commit ad3793fc3945173f64d82d05d3ecde41f6c0435c upstream.

Rather than having DAX support be unique by setting it based on table
type in dm_setup_md_queue().
