From: Thomas Gleixner Date: Tue, 21 May 2019 16:35:12 +0200 Subject: [PATCH] workqueue: Make alloc/apply/free_workqueue_attrs() static Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.2/older/patches-5.2.9-rt3.tar.xz None of those functions have any users outside of workqueue.c. Confine them.
