[PATCH v2 08/22] futex: Rename: {get,cmpxchg}_futex_value_locked()

["André Almeida" <andrealmeid@collabora.com>]

From: Peter Zijlstra <peterz@infradead.org>

In order to prepare introducing these symbols into the global
namespace; rename them:

 s/\<\([^_ ]*\)_futex_value_locked/futex_\1_value_locked/g
