If the value is not monotonically increasing but is reset to 0 at some
point, this might lead to problems in tcp_write_timeout().
It's the only idea I have now.

Your idea is good.

Logs corresponding on http://wwW.starox.org/pub/scp_stall is .10

I make 2 attempts. Printk corresponding to .10 are those after the line
