Subject: [PATCH 03/11] tools/kernel.h: extend with dummy RCU functions
Date: Mon, 17 Feb 2020 21:41:25 -0500 [thread overview]
Message-ID: <20200218024133.5059-4-sashal@kernel.org> (raw)
In-Reply-To: <20200218024133.5059-1-sashal@kernel.org>
These calls were added by 108c14858b9e ("locking/lockdep: Add support
for dynamic keys") and require no special handling in userspace, so just
add empty function definitions.
Signed-off-by: Sasha Levin <sashal@kernel.org>
