    Subject[PATCH v2 0/7] pid: Introduce helper task_is_in_root_ns()
    Date
    The kernel uses open code to check if a process is in root PID namespace
    or not in several places.

    Suggested by Suzuki, this patch set is to create a helper function
    task_is_in_init_pid_ns() to replace open code.

    This patch set has been applied on the mainline kernel and built for
    Arm64 kernel with enabling all relevant modules.

    Changes from v1:
    * Renamed helper function from task_is_in_root_ns() to
    task_is_in_init_pid_ns(). (Leon Romanovsky)
    * Improved patches' commit logs for more neat.


    Leo Yan (7):
    pid: Introduce helper task_is_in_init_pid_ns()
    coresight: etm3x: Use task_is_in_init_pid_ns()
    coresight: etm4x: Use task_is_in_init_pid_ns()
    connector/cn_proc: Use task_is_in_init_pid_ns()
    coda: Use task_is_in_init_pid_ns()
    audit: Use task_is_in_init_pid_ns()
    taskstats: Use task_is_in_init_pid_ns()
