From a32e01ee689794a26bdfdbaa7e8c334576cee36c Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Wed, 17 Jan 2018 06:24:30 -0800 Subject: rcu: Use wrapper for lockdep asserts Commits c0b334c5bfa9 and ea9b0c8a26a2 introduced new sparse warnings by accessing rcu_node->lock directly and ignoring the __private marker. Introduce a new wrapper and use it. Also fix a similar problem in srcutree.c introduced by a3883df3935e. Signed-off-by: Matthew Wilcox Signed-off-by: Paul E.
