[LTP] [PATCH 1/1] tst_test: Fix tests using device without .filesystems

[Petr Vorel]

cce618891 introduced a regression for tests which use the test loop
device (e.g. .mount_device = 1 or .format_device = 1) without
.filesystems array (execveat03, ioctl04, inotify0[378], fanotify10,
mount02, umount0[1-3], umount2_02).

Call in that case prepare_device() with the default filesystem type.

Fixes: cce618891 ("lib: tst_test: Add per filesystem mkfs and mount opts")

Hi,

is there a more elegant way to fix this?

Kind regards,
Petr
