Message-ID: <20071205193727.24437.79998.stgit@warthog.procyon.org.uk>
Date: Wed, 05 Dec 2007 19:37:27 +0000
From: David Howells <dhowells@...hat.com>
To: viro@....linux.org.uk, hch@...radead.org,
Trond.Myklebust@...app.com, sds@...ho.nsa.gov,

Subject: [PATCH 5/7] Security: Change current->fs[ug]id to current_fs[ug]id()
Change current->fs[ug]id to current_fs[ug]id() so that fsgid and fsuid can be
separated from the task_struct.
