From f9425ad4e5c8f8f9f6297d0358dc44ca058ffe47 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Fri, 4 May 2012 14:33:06 +0100 Subject: GFS2: Fix sgid propagation when using ACLs This cleans up the mode setting code when creating inodes. The SGID bit was being reset by setattr_copy() when the user creating a subdirectory was not in the owning group. When ACLs are in use this SGID bit should have been propagated if the ACL allows creation of a subdirectory. GFS2's behaviour now matches that of the other ACL supporting filesystems in this regard.
