  SVN rev 196197 on 2009-08-13 17:51:26Z by jhb
  
  MFC: Fix some LORs between vnode locks and filedescriptor table locks.
  - Don't grab the filedesc lock just to read fd_cmask.
  - Drop vnode locks earlier when mounting the root filesystem and before
    sanitizing stdin/out/err file descriptors during execve().
