Which bugfix do you mean? If you mean the preempt fix for the NOTSC improvement it makes no sense to split it up from the NOTSC part. There are no other bugfixes (the reduction of the notsc window isn't strictly a bugfix, since the feature already helped).
I can split the API change from the NOTSC feature, I'll wait some more days in the hope this one goes in. If it doesn't go in I'll follow your suggestion and I'll try again later with the split up in the hope to increase my chances.
From my point of view it's not urgent to merge it, it's just the anti-seccomp advocates that should want this patch being merged urgently. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
