Revision c3293a9ac2a4f9160b85b5e986a8e0c54986e7f7 authored by Matias Bjørling on 29 December 2015, 13:37:56 UTC, committed by Jens Axboe on 29 December 2015, 15:28:32 UTC
dev->nr_luns reports the total number of luns available in a device while dev->luns_per_chnl is the number of luns per channel. When multiple channels are available, the offset is calculated from a channel and lun id into a linear array. As it multiplies with the total number of luns, we go out of bound when channel id > 0 and causes the kernel to panic when we read a protected kernel memory area.
