Subject: [PATCH v2 0/7] pid: Introduce helper task_is_in_root_ns()

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()
