From db78b877f7744bec4a9d9f9e7d10da3931d7cd39 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 4 Jun 2010 11:30:03 +0200 Subject: always call inode_change_ok early in ->setattr Make sure we call inode_change_ok before doing any changes in ->setattr, and make sure to call it even if our fs wants to ignore normal UNIX permissions, but use the ATTR_FORCE to skip those.
