[PATCH net v3 0/2] pid: Introduce helper task_is_in_root_ns()

[Leo Yan]

This patch series introduces a helper function task_is_in_init_pid_ns()
to replace open code.  The two patches are extracted from the original
series [1] for network subsystem.

As a plan, we can firstly land this patch set into kernel 5.18; there
have 5 patches are left out from original series [1], as a next step,
I will resend them for appropriate linux-next merging.

Changes from v1:
