From 1b23f02cf4bbe644028077539b1045f742d61fa2 Mon Sep 17 00:00:00 2001 From: Tymoteusz Kielan Date: Mon, 25 Jul 2016 13:38:01 -0700 Subject: [PATCH] IB/hfi1: Fix to fully initialize send context area While handling buffer control MAD, partially initialized dd->kernel_send_context area may cause potential dereference of uninitialized pointers. Fix by using kzalloc_node() instead of kmalloc_node().
