There are several functions which have no opportunity to retun an error, and don't contain any ASSERTs which could be argued to be better constructed as error cases. So, make them voids to simplify the callers. Signed-off-by: Eric Sandeen <sandeen@redhat.com> --- I had sent this a while back, and Darrick had concerns about a few functions which maybe /should/ return errors; I tried to avoid changing anything which was remotely close to that case, and stick to the simple/obvious ones.
