1729  ret = 0
1731  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
1732  nlsk = fetch RCU-protected pointer for dereferencing(nlsk)
1733  If nlsk Then ret = netlink_has_listeners(nlsk, XFRMNLGRP_ACQUIRE)
1735  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
