  Modified files:
    sys/nfs              nfs_vnops.c 
  Log:
  Fix two bugs in nfs_readdirplus(). The first is that in some cases,
  vnodes are locked and never unlocked, which leads to processes starting
  to wedge up after doing a mount -o nfsv3,tcp,rdirplus foo:/fs /fs; ls /fs.
  The second is that sometimes cnp is accessed without having been
  properly initialized: cnp->cn_nameptr points to an earlier name while
  "len" contains the length of a current name of different size. This
  leads to an attempt to dereference *(cn->cn_nameptr + len) which will
  sometimes cause a page fault and a panic.
  
  With these two fixes, client side readdirplus works correctly with
  FreeBSD, IRIX 6.5.4 and Solaris 2.5.1 and 2.6 servers.
