...it locks the leaf? Really?
...so how does a news server that uses getfh() on all those inodes,
doing its own caching routines avoid panicking the kernel?
I don't necessarily doubt you, but I'm rather surprised that it
locks the node; after all fhstat() will fail if the file referred
to by the handle gets mysteriously unlink()ed.
