From mboxrd@z Thu Jan 1 00:00:00 1970 From: Josef Bacik Subject: [PATCH] Btrfs: noinline the cluster searching functions Date: Wed, 25 May 2011 13:08:59 -0400 Message-ID: <1306343339-25979-1-git-send-email-josef@redhat.com> To: linux-btrfs@vger.kernel.org Return-path: List-ID: When profiling the find cluster code it's hard to tell where we are spending our time because the bitmap and non-bitmap functions get inlined by the compiler, so make that not happen.
