btrfs-progs: test: add simple test for 'fi du' recursion depth The documentation lacks clarity about depth to which recursive 'fi du' goes, and was pointed out by a user. Add test that creates another mount inside a filesystem and verifies that 'fi du' does not go there. Issue: #185 Signed-off-by: David Sterba <dsterba@suse.com>

#!/bin/bash
# check how deep does recursive 'fi du' go, currently it has to stop at
# mountpoint and can continue to subvolumes
btrfs-progs: tests: add protection against running out of test suite Executing the script inside the directories as './test.sh' is not supposed to work but could happen accidentally. With an exit after attempting to source the we can fix that. Signed-off-by: David Sterba <dsterba@suse.com>
