.PP
Control will return to the caller some time after a full grace
period has elapsed, in other words after all currently executing RCU
read-side critical sections have completed.  RCU read-side critical
sections are delimited by \fBrcu_read_lock\fR and \fBrcu_read_unlock\fR,
and may be nested.
.PP
If your read-side code is not protected by \fBrcu_read_lock\fR, do -not-
use \fBsynchronize_rcu\fR\&.
