[LTP] [PATCH v3, 1/2] lib/tst_test.sh: Make tst_umount work with argument that has trailing slash

[Petr Vorel <pvorel@suse.cz>]

> Hi Leo

> > /proc/mounts shows the mount point without trailing slashes, e.g.
> > ~ $ cat /proc/mounts
> > xxx /root/cgroup cgroup rw,relatime,cpu 0 0

> > So current tst_umount would not work with argument that has trailing slash, e.g.
> > tst_umount cgroup/ would give "The device is not mounted".

> > Fix this by filtering out the trailing slash before grepping /proc/mounts.
