Subject: [PATCH] add hook to generic irq code (free_irq)
Date: Tue, 19 Oct 2004 19:31:56 -0700 [thread overview]
Message-ID: <20041020023156.GA8597@taniwha.stupidest.org> (raw)
This is needed because some architectures (well, presently only UML)
needs to be notified as things are freed.
Signed-off-by: cw@f00f.org
I can't say I'm 100% happy about this, either the name or a somewhat
ugly hook that is called with a spinlock held but for lack of any
better suggestions...
