+.Sh DESCRIPTION
+The
+.Fn vwaitforio
+call sleeps until all asynchronous writes associated with the vnode
+.Fa vp
+finish.
+This is used by functions that need to make sure

+The
+.Fn vwaitforio
+call sleeps at priority
+.Dv PRIBIO
++ 1.
+The
+.Fa slpflag ,
+.Fa wmesg ,
+and
+.Fa slptimeo
+arguments indicate flags to be passed to
+.Xr tsleep_nsec 9 .
+.Pp
+This function must be called at
+.Xr splbio 9 .
+.Pp
+It may be important to ensure that no other process submits asynchronous
+writes while a process is waiting for I/O on this vnode.
+Otherwise,
+.Fn vwaitforio
+may never return.
+.Sh RETURN VALUES
+The
+.Fn vwaitforio
+function returns 0 on success.
+See
+.Xr tsleep 9
+for possible error returns.
