From d2f31a5fd60d168b00fc4f7617b68a1287b21e90 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 13 Jun 2011 20:19:27 +0200 Subject: blk-throttle: Make total_nr_queued unsigned The total of two unsigned values should also be unsigned. Update throtl_log output to unsigned. Update total_nr_queued test to non-zero to be the same as the other total_nr_queued tests.
