> - blk_queue_max_discard_sectors(brd->brd_queue, UINT_MAX); > + blk_queue_max_discard_sectors(brd->brd_queue, UINT_MAX >> 9); Shouldn't we fix the issue by capping to UINT_MAX >> 9 inside blk_queue_max_discard_sectors? That way we'll prevent against having issues like this in any other driver as well.
