CVS commit: src/sys/kern

Module Name:    src
Committed By:   ad
Date:           Tue May  6 12:51:22 UTC 2008

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

Log Message:
Fix a couple of problems with checkdirs():

- vnode and cwd locks were being taken with proc_lock held, which is bad
  because proc_lock can only be held for a short period of time.

- Processes could have continually forked and escaped notice, keeping
  a reference to the old directory on top of which a new mount exists.
