[LTP] [PATCH] tst_supported_fs: Implement checking paths against skiplist

[Petr Vorel]

Hi all,

> Implement tst_supported_fs feature suggested by pvorel in his patch:
> tst_test.sh: Fix filesystem support detection
FYI there is still be need to detect filesystem in particular directory in
ima_setup.sh [1] to avoid df dependency:

if [ "$(df -T $TMPDIR | tail -1 | awk '{print $2}')" != "tmpfs" -a -n "$TST_NEEDS_DEVICE" ]; then
	unset TST_NEEDS_DEVICE
fi

But I guess I'll just reuse the exit code of: ./tst_supported_fs -d $TMPDIR -s "tmpfs"

Kind regards,
Petr
