From c0b942a76361e08fc9fb17989e0f266e64ff0688 Mon Sep 17 00:00:00 2001 From: Nicolas Iooss Date: Mon, 12 Dec 2016 16:40:39 -0800 Subject: [PATCH] kthread: add __printf attributes When commit fbae2d44aa1d ("kthread: add kthread_create_worker*()") introduced some kthread_create_...() functions which were taking printf-like parametter, it introduced __printf attributes to some functions (e.g. kthread_create_worker()). Nevertheless some new functions were forgotten (they have been detected thanks to -Wmissing-format-attribute warning flag). Add the missing __printf attributes to the newly-introduced functions in order to detect formatting issues at build-time with -Wformat flag.
