Subject: [PATCH v21 11/19] refs.c: make remove_empty_directories always set errno to something sane
Date: Mon, 14 Jul 2014 13:58:53 -0700	[thread overview]
Message-ID: <1405371541-32121-12-git-send-email-sahlberg@google.com> (raw)
In-Reply-To: <1405371541-32121-1-git-send-email-sahlberg@google.com>

Making errno when returning from remove_empty_directories() more
obviously meaningful, which should provide some peace of mind for
people auditing lock_ref_sha1_basic.
