From 84f90ab5d3e859cced1d7b080adc4ea562ca2eaa Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Wed, 15 Oct 2025 14:36:33 +0200 Subject: [PATCH] pid: introduce task_ppid_vnr() helper Cosmetic change. Unlike all other similar helpers task_ppid_nr_ns() doesn't have a _vnr() version; add one for consistency.
