From 1a3f25f02eff8955f6b402ff6e27df47067fe440 Mon Sep 17 00:00:00 2001 From: Christoph Paasch Date: Wed, 23 Oct 2013 12:49:21 -0700 Subject: [PATCH] net: Dereference pointer-value of sk_prot->memory_pressure 301559ce7c (tcp_memcontrol: Kill struct tcp_memcontrol) falsly modified the access to memory_pressure of sk->sk_prot->memory_pressure. The patch did modify the memory_pressure-field of struct cg_proto, but not the one of struct proto. So, the access to sk_prot->memory_pressure should not be changed.
