From: Jeff Mahoney <je...@suse.com>
* tests/file_ioctl.c: New file.
* tests/file_ioctl.test: New file.
* tests/Makefile.am: Add it.
This is limited to FIEMAP. FICLONE* and FIDEDUPERANGE originated in
btrfs and will be tested there.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
