Date: Thu, 5 Apr 2007 12:44:03 +0200 From: Andi Kleen <ak@...e.de> To: davem@...emloft.net Cc: netdev@...r.kernel.org Subject: [PATCH] Uninline tcp_done The function is quite big and has several call sites and nothing to collapse by compiler optimization on inlining. Besides it's nicer to read in a in .c file.
