[LTP] [PATCH 1/1] syscalls/ioctl08: Require btrfs

[Petr Vorel <pvorel@suse.cz>]

Hi Amir,

> Test requires btrfs otherwise it fails:
> WARNING: failed to open /dev/btrfs-control, skipping device
> registration: No such file or directory
> safe_macros.c:757: BROK: tst_test.c:752: mount(/dev/loop0, mnt_point,
> btrfs, 0, (nil)) failed: ENODEV
could you please test it?

Kind regards,
Petr
