SYNCHRONIZE_RCU(9)                        Driver Basics                        SYNCHRONIZE_RCU(9)



NAME
       synchronize_rcu - wait until a grace period has elapsed.

SYNOPSIS
       void synchronize_rcu(void);

ARGUMENTS
       void
           no arguments

DESCRIPTION
       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.
       Note, however, that upon return from synchronize_rcu, the caller might well be executing
       concurrently with new RCU read-side critical sections that began while synchronize_rcu was
       waiting. RCU read-side critical sections are delimited by rcu_read_lock and
       rcu_read_unlock, and may be nested.

       See the description of synchronize_sched for more detailed information on memory ordering
       guarantees.
