commit 1bb6119939711861a021ef2550a7a294db4cbf9a
Author: Matthew Dillon <dillon@apollo.backplane.com>

    Fix a bug in vinvalbuf().  vinvalbuf() is usually called when attempting
    to reclaim a vnode but can sometimes be called with V_SAVE when attempting
    to make a vnode reclaimable.  In the latter case write races with other
    threads can create new dirty buffers after the FSYNC returns.
    
    Only assert that dirty buffers are not present if the vnode is undergoing
    reclamation.
