[PATCH RFC tip/core/rcu 02/23] rcu: add __rcu API for later sparse checking
in [Kernel]

Prev: Buildfailure for omap3_defconfig due to patch OMAP: RX51: Add LCD Panel support
Next: [PATCH RFC tip/core/rcu 15/23] radix-tree: __rcu annotations
From: Paul E. McKenney on 12 May 2010 17:40 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.
