        sys/fs/smbfs/smbfs_vfsops.c: revision 1.64
In sync, skip vnodes which have a null v_data pointer.  This is a
workaround for the problem analyzed more deeply in kern/30831.  In
short, the problem is keeping the vnode on the mount point vnode
list during reclaim.  If reclaim happens to sleep (as is a possibility
with smbfs due to calling vrele() and therefore possibly VOP_INACTIVE),
code going through the entire mountpoint vnode list will hit
half-reclaimed vnodes.
