From 31e6d363abcd0d05766c82f1a9c905a4c974a199 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 17 Jun 2009 19:05:41 -0700 Subject: net: correct off-by-one write allocations reports commit 2b85a34e911bf483c27cfdd124aeb1605145dc80 (net: No more expensive sock_hold()/sock_put() on each tx) changed initial sk_wmem_alloc value. We need to take into account this offset when reporting sk_wmem_alloc to user, in PROC_FS files or various ioctls (SIOCOUTQ/TIOCOUTQ) Signed-off-by: Eric Dumazet Signed-off-by: David S.
