vnrlu_proc: vnode recycler stopped working!

[Matthew Dillon]

    Were both of you guys doing major filesystem operations on the root
    mount?

    From looking at Peter's core the root mount point doesn't have a syncer
    vnode, and the new vnode recycling code won't run on it because of that.
    I am fixing it now.

    What is interesting is that the vnode recycling code is not in error
    here, but instead has exposed a long standing issue in the code where
    the syncer was not running on the root filesystem every 30 seconds like
    it was supposed to.
