cred = current_cred - Access the current task's subjective credentials* Access the subjective credentials of the current task. RCU-safe,* since nobody else can modify it.()

_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

pcred = __task_cred - Access a task's objective credentials*@task: The task to query* Access the objective credentials of a task. The caller must hold the RCU* readlock.* The result of this function should not be passed directly to get_cred();(p)

match = uid_eq( effective UID of the task , effective UID of the task ) || uid_eq( effective UID of the task , real UID of the task )

_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()
