Subject[PATCH RFC tip/core/rcu 02/23] rcu: add __rcu API for later sparse checking
Date
This commit defines an __rcu API, but provides only vacuous definitions
for it. This breaks dependencies among most of the subsequent patches,
allowing them to reach mainline asynchronously via whatever trees are
appropriate.
