Subject: [PATCH v2 3/8] Cygwin: Move post-dir unlink check
Date: Wed, 20 Jan 2021 17:10:51 +0100 [thread overview]
Message-ID: <20210120161056.77784-4-ben@wijen.net> (raw)
In-Reply-To: <20210115134534.13290-1-ben@wijen.net>
Move post-dir unlink check from fhandler_disk_file::rmdir to
_unlink_nt_post_dir_check
If a directory is not removed through fhandler_disk_file::rmdir
we can now make sure the post dir check is performed.
