Subject: [PATCH review 29/85] gfs2: Report quotas in the caller's user namespace.

From: "Eric W. Biederman" <ebiederm@...ssion.com>

When a quota is queried return the uid or the gid in the mapped into
the caller's user namespace.  In addition perform the munged version
of the mapping so that instead of -1 a value that does not map is
reported as the overflowuid or the overflowgid.
