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

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").

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.
