commit ba9d293ccf524b12c4f03cdb6a6acab3e46bc696
Author: Jeremy Allison <jra at samba.org>
Date: Wed Aug 22 13:37:04 2018 -0700
s3: smbd: Ensure dirpath is set to ".", not "\0" so it is always a valid path.
Cleanup of the internals of unix_convert().
Ensure check_parent_exists() returns this in the non-optimization
case. Ensure unix_convert() initializes dirpath to ".".
