From c9e8d128fe316751230ee0c53478740c64f58436 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Thu, 7 Nov 2013 10:45:35 -0800 Subject: percpu-refcount: Add EXPORT_SYMBOL to use percpu_ref from modules This patch adds EXPORT_SYMBOL() for percpu_ref_init(), percpu_ref_cancel_init() and percpu_ref_kill_and_confirm() so that percpu refcounting can be used by external modules.
