593  res = all under rcu_read_lock
594  If Value is more likely to compile time(!res) Then Return true
596  If Value for the false possibility is greater at compile time(res < 0) Then
597  _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()
598  mntput(bastard)
599  _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
