The

function flushes all dirty buffers associated with the vnode

to the disk.
If the

argument is zero, writes to the disk will be asynchronous and

returns immediately; otherwise, writes will be synchronous and all
disk blocks associated with the vnode will have been properly
synchronized with the in-core buffers upon return.
