locking: Make sparse work with inline spinlocks and rwlocks 2010-03-13T00:21:21+00:00 Luca Barbieri luca@luca-barbieri.com 2010-03-11T22:08:45+00:00 b97c4bc16734a2e597dac7f91ee9eb78f4aeef9a Currently sparse does not work with inline spinlock and rwlock functions. The problem is that they do not use the __acquires/__releases out-of-line functions, but use inline functions with no sparse annotations. This patch adds the appropriate annotations to make it work properly.
