Subject: [PATCH 4.9 26/96] tun: remove unnecessary memory barrier
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Timur Celik <mail@...urcelik.de>
[ Upstream commit ecef67cb10db7b83b3b71c61dbb29aa070ab0112 ]
Replace set_current_state with __set_current_state since no memory
barrier is needed at this point.
