From 208da78e8ec8b6d6ce3747ab0e5c120458e08ae6 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Thu, 17 Nov 2016 12:50:23 +0100 Subject: [PATCH 1/4] scsi: libfc: fix seconds_since_last_reset miscalculation Commit 540eb1eef0ab ("scsi: libfc: fix seconds_since_last_reset calculation") removed the use of 'struct timespec' from fc_get_host_stats(). This broke the output of 'fcoeadm -s' after kernel 4.8-rc1.

As the controllers are now placed on the same bus as the internal disks this leads to a clash with the SCSI target id of controller. This patch checks the SCSI revision, and moves older controller to bus '3' to be compatible with older releases and avoid this problem.
