From 0cd397d33608ae6c97d2ee6c8c43462b419b7e26 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Sun, 25 Oct 2009 19:03:51 -0700 Subject: rcu: Add synchronize_srcu_expedited() This patch creates a synchronize_srcu_expedited() that uses synchronize_sched_expedited() where synchronize_srcu() uses synchronize_sched(). The synchronize_srcu() and synchronize_srcu_expedited() functions become one-liners that pass synchronize_sched() or synchronize_sched_expedited(), repectively, to a new __synchronize_srcu() function. While in the file, move the EXPORT_SYMBOL_GPL()s to immediately follow the corresponding functions. Requested-by: Avi Kivity Tested-by: Marcelo Tosatti Signed-off-by: Paul E.
