From: Keith Busch Date: Tue, 18 Sep 2018 23:58:37 +0000 (-0600) Subject: PCI: Uninline PCI bus accessors for better ftracing X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5180fd913558825e910e255d879232c63aaa5c24;p=linux.git PCI: Uninline PCI bus accessors for better ftracing The PCI bus config accessors could be inlined into other accessor functions, which makes it so they can't be traced. Force them to never be inlined so that ftrace can hook into these functions.
