Subject: [PATCH] compile time initialization for event flags value
Date: Wed, 26 Jan 2011 16:49:00 +0800 [thread overview]
Message-ID: <4D3FDFFC.6030304@cn.fujitsu.com> (raw)
compile time initialization is better than runtime initialization.
impact: remove many early_initcall()s and many trace_init_flags_##name()s.
