It's currently unlikely that we will ever end up with more than 4 billion inodes waiting for reclamation, but the fs object code uses long int for object counts and we're certainly capable of generating that many. Instead of truncating the internal counters, widen them and report the object counts correctly. Signed-off-by: Darrick J.
