From f2ebfbc991044fd5b89d4529741d7500feb37fbd Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Sat, 13 Oct 2012 01:14:15 +0800 Subject: [PATCH] srcu: Export process_srcu() Because process_srcu() will be used in DEFINE_SRCU(), which is a macro that could be expanded pretty much anywhere, it can no longer be static. Note that process_srcu() is still internal to srcu.h. Signed-off-by: Lai Jiangshan Signed-off-by: Paul E.
