From 88437879fbd0ac5cde3f683f8eee455bbf83aaac Mon Sep 17 00:00:00 2001 From: Lars Ellenberg Date: Thu, 14 Jun 2012 15:19:26 +0200 Subject: [PATCH] drbd: reset congestion information before reporting it in /proc/drbd We cache the congestion status in mdev->congestion_reason whenever drbd_congested() was called. Reset this cached info before reporting it when reading /proc/drbd.
