From e4fd5da39f99d5921dda1fe3d93652fbd925fbfd Mon Sep 17 00:00:00 2001 From: Pavel Emelianov Date: Tue, 29 May 2007 13:19:18 -0700 Subject: [TCP]: Consolidate checking for tcp orphan count being too big. tcp_out_of_resources() and tcp_close() perform the same checking of number of orphan sockets. Move this code into common place. Signed-off-by: Pavel Emelianov Signed-off-by: David S.
