CVS commit: src

Module Name:    src
Committed By:   hannken
Date:           Wed Jul 21 09:01:36 UTC 2010

Modified Files:
        src/share/man/man9: namecache.9
        src/sys/kern: vfs_cache.c vfs_getcwd.c

Log Message:
Using cache_revlookup() leads to vnode races as it returns an unreferenced
vnode that may disappear before the caller has a chance to reference it.

Reference the vnode while the name cache is locked.

No objections on tech-kern.
