Subject: exit-post-hook-unlock.sh: exit gracefully if LOCKDIR does not exist
X-Git-Url: https://git.ao2.it/experiments/hook-lock.git/commitdiff_plain/2144a1fa25d58c93677c110bcbfdc58023d0cf45?hp=6e3f2c8a7097aeccd1b7bda32e1b058a947e5c78

exit-post-hook-unlock.sh: exit gracefully if LOCKDIR does not exist

If LOCKDIR does not exist it means that the lock is not active so
there's no need to do anything.
