I've applied this, but I have two complaints: 1) Two had to be hand applied, it wasn't against the block tree. 2) The ordering of the signed-off-by. Someone told me that this is patchwork, but I absolutely hate it. SOB should go last, not before the reviewed-by. I fixed that up too. -- Jens Axboe -- dm-devel mailing list dm-devel@redhat.com https://www.redhat.com/mailman/listinfo/dm-devel
