_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

3279

Return in pmask the portion of a cpusets's cpus_allowed that* are online. If none are online, walk up the cpuset hierarchy* until we find one that does have some online cpus.* One way or another, we guarantee to return some non-empty subset

3280

_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()
