Regrading the average delay of a ping request task - we need to have
the average delay, but we're interested only in the average delay of
pings that were sent lately (i.e. not pings that were sent a year
ago). Am I right?
I thought about having a cyclic array of delays in the kernel. It can

open-iscsi sends nop-outs to the target. If the target responds quick
enough, we don't get a timeout. I'd like to know (for internal debug
purposes) how many times the ping timer almost expired. This sounds
like a useful feature also for other open-iscsi developers/users.
I was thinking about

as well, but standard deviation probably requires use of the FPU, so that's not
possible in kernel modules (AFAIK)).
