src/sys/kern: vfs_lookup.c
Log Message:
lookup_fastforward():
- If the root vnode of a mount is being reclaimed concurrent to a lookup,
it's possbile to become confounded and bail out of the loop with both
foundobj=NULL and searchdir=NULL (causing a NULL pointer deref). If that
happens everything should be rolled back to the start for retry. Problem
found and debugged by hannken@.
- If the terminal node was !VDIR then searchdir was needlessly referenced.
No functional impact.
