Subject: [PATCH] util: Move virIsDevMapperDevice() to virdevmapper.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When introducing virdevmapper.c (in v4.3.0-rc1~427) I didn't
realize there is a function that calls in devmapper. The function
is called virIsDevMapperDevice() and lives in virutil.c. Now that
we have a special file for handling devmapper move it there.

Conflicts:
- src/util/virutil.c - Context, becasue v6.0.0-206-gfc920f704c is
  not backported.
