Errm.... Looking at nfs4_reset_session, wouldn't it make sense to move
that 'out:' label down one line, so that we can get rid of that test for
'status == 0'?

This is not related directly to your patch, but "sparse" is going to
have a field day with all these scattered around the place. Are there
any plans to clean all this up, and replace those 'int' and 'unsigned'
declarations that are being assigned big ended values with the correct
'__be32' type?
