Subject: percpu-refcount: Add EXPORT_SYMBOL to use percpu_ref from modules
X-Git-Tag: v3.13-rc1~5^2~23
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c9e8d128fe316751230ee0c53478740c64f58436;hp=dbcbc95cd85854588ac80c0a6d98586fa2129418;p=karo-tx-linux.git

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.
