CVS commit: src/sys/kern

[Chuck Silvers <chs%netbsd.org@localhost>]

Module Name:    src
Committed By:   chs
Date:           Wed Dec 27 23:21:02 UTC 2006

Modified Files:
        src/sys/kern: vfs_lookup.c

Log Message:
fix two more problems in the recent changes to lookup():
 - don't hold the parent directory vnode locked while traversing mount points.
   the fs that's mounted might be an NFS served by a userland process
   like the automounter, which might need to traverse the parent directory
   in order to complete the lookup.
 - in the ENAMETOOLONG case fixed in rev. 1.75, set ni_dvp to dp
   since we've logically moved on to using "dp" as the parent.
   the caller will then handle vput()ing it as normal.
   this fixes PR 35279.
