| H A D | super.c | eedfd73d Fri Jul 17 02:20:50 CDT 2020 Ira Weiny <ira.weiny@intel.com> drivers/dax: Expand lock scope to cover the use of addresses
The addition of PKS protection to dax read lock/unlock will require that
the address returned by dax_direct_access() be protected by this lock.
Correct the locking by ensuring that the use of kaddr and end_kaddr
are covered by the dax read lock/unlock.
