(From update of attachment 9158)
This looks good and should be landed to b1_4 and b1_5, only to maintain better
patchless client compatibility, in lookup_it_finish it is worth calling
d_rehash and d_drop. Also dmove and d_rehash in ll_find_alias outside of
dcache_lock.
Please attach revised patch here too.
