There were a few things I missed -- a couple of static inline directory functions that have to be exported for xfs_repair; a couple of directory naming functions that make porting much easier if they're /not/ static inline; and a u16 usage that should have been uint16_t. None of these things are bugs in their own right; this just makes porting xfsprogs easier. Signed-off-by: Darrick J.
