Hi Mikhail, According to the guide of submitting patches [1], "Signed-off-by" can only be used by patch author and people handling and transporting the patch, so Ping-Ke said he may change your s-o-b into "Reviewed-by:" or other suitable tag. We would appreciate your kind understanding. [1] https://github.com/torvalds/linux/blob/master/Documentation/process/submitting-patches.rst
