From 2b885517110cbe8724fef30363778b6284d0a428 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 11 Mar 2016 17:34:53 +0100 Subject: block: bio_remaining_done() isn't unlikely We use bio chaining during most I/Os these days due to the delayed bio splitting. Additionally XFS will start using it, and there is a pending direct I/O rewrite also making heavy use for it. Don't pretend it's always unlikely, and let the branch predictor do it's job instead.
