[PATCH v4 0/5] pid: Use helper task_is_in_root_ns()

[Leo Yan <leo.yan@linaro.org>]

The helper task_is_in_root_ns() has been merged into the mainline kernel
(thanks Jakub Kicinski for merging the patches [1]).

On the other hand, there have 5 patches were left out in the patch
series v2 [2], this patch series is to resend these 5 patches so that
sub-module maintainers could pick patches without concerning dependency
issue.

This patch series can be cleanly applied on the mainline kernel with
latest commit dcb85f85fa6f ("gcc-plugins/stackleak: Use noinstr in favor
of notrace").

[2] https://lore.kernel.org/lkml/20211208083320.472503-1-leo.yan@linaro.org/

Changes from v2:
* Added review and ack tags.
* Dropped two merged patches and resend the left 5 patches.

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.
