SubjectRe: [PATCH net 0/7] rxrpc, afs: Fix probing issues

> Here are some fixes for rxrpc and afs to fix issues in the RTT measuring in
> rxrpc and thence the Volume Location server probing in afs:
>
> (1) Move the serial number of a received ACK into a local variable to
> simplify the next patch.
>
> (2) Fix the loss of RTT samples due to extra interposed ACKs causing
> baseline information to be discarded too early. This is a particular
> problem for afs when it sends a single very short call to probe a
> server it hasn't talked to recently.
>
> (3) Fix rxrpc_kernel_get_srtt() to indicate whether it actually has seen
> any valid samples or not.
>
> (4) Remove a field that's set/woken, but never read/waited on.
>
> (5) Expose the RTT and other probe information through procfs to make
> debugging of this stuff easier.
>
> (6) Fix VL rotation in afs to only use summary information from VL probing
> and not the probe running state (which gets clobbered when next a
> probe is issued).
>
> (7) Fix VL rotation to actually return the error aggregated from the probe
> errors.

> The patches are tagged here:
