[PATCH tip/core/rcu 02/24] rcu: Remove KCSAN stubs from update.c

From: paulmck
Date: Mon Aug 31 2020 - 14:02:53 EST


From: "Paul E. McKenney" <paulmck@xxxxxxxxxx>

KCSAN is now in mainline, so this commit removes the stubs for the
data_race(), ASSERT_EXCLUSIVE_WRITER(), and ASSERT_EXCLUSIVE_ACCESS()
macros.
