Date: Tue, 13 Mar 2012 00:23:27 -0700 From: Maciej Żenczykowski <zenczykowski@...il.com> To: David Miller <davem@...emloft.net> Cc: netdev@...r.kernel.org Subject: Re: [PATCH] net: pfifo_fast - use ffs(x)-1 instead of array lookup I was actually leaning towards going with ffs()-1, since it's excellent on x86-64 good on x86_cmov decent on x86 good on armv5+ and I'm guessing it'll be good or better on any modern platform -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
