Jeff Roberson eb1314a249 - cache dp->i_offset in the local 'i_offset' variable for use in loop ... indexes so directory lookup becomes shared lock safe. In the modifying cases an exclusive lock is held here so the commit routine may rely on the state of i_offset. - Similarly handle i_diroff by fetching at the start and setting only once the operation is complete. Without the exclusive lock these are only considered hints. - Assert that an exclusive lock is held when we're preparing for a commit routine. - Honor the lock type request from lookup instead of always using exclusive locking.
