- Log -----------------------------------------------------------------
commit d2da9dee686881106678d50a96713f0632dcdf10
Author: Jeremy Allison <jra at samba.org>
Date: Thu Jun 18 15:07:14 2009 -0700
Add some const to the stat struct in the dosmode calls.
Fix a couple more unix_convert uses to filename_convert.
Fix bug in acl_group_override() where an uninitialized
struct could be used. Move unix_convert with wildcard
use in SMBsearch reply to boilerplate code.
Jeremy.
