SubjectRe: [PATCH] libata: use WARN_ON_ONCE on hot paths
2009/1/9 Tejun Heo <tj@kernel.org>:
> Convert WARN_ON() on command issue/completion paths to WARN_ON_ONCE()

Hi

I've not yet applied this patch - but now I'm getting these WARNS on my T61:
(commit: 2150edc6c5cf00f7adb54538b9ea2a3e9cedca3f)

Is this patch solving the problem or just hiding warnings ?
