From adcfe1964e627b62fbc6e45609b1f0db2c64dd14 Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Sat, 27 Mar 2010 17:15:29 -0700 Subject: net: increase preallocated size of nlmsg to accomodate for IFLA_STATS64 When more data is stuffed into an nlmsg than initially projected, an extra allocation needs to be done. Reserve enough for IFLA_STATS64 so that this does not to needlessy happen. Signed-off-by: Jan Engelhardt Signed-off-by: David S.
