_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

267

ac = fetch RCU-protected pointer for dereferencing(struct auditd_connection - kernel/auditd connection state*@pid: auditd PID*@portid: netlink portid*@net: the associated network namespace*@rcu: RCU head* Description:* This struct is RCU protected; you must either hold the RCU lock for reading)

268

If Not ac || Not pid Then pid = 0

270

Else pid = pid_vnr(pid)

272

_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()
