From c09c7237eadc65916305835ca1e3ee8a03f01159 Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Thu, 17 Jan 2008 00:38:29 +0100 Subject: [PATCH] rc80211-pid: fix last_sample initialization Fix last_sample initialization. kzalloc'ing the per-STA data wasn't enough, as jiffies can assume negative values as well. This fixes a bug which prevented correct PID operation for a while after booting. Thanks to Michael Buesch for reporting this.
