Re: [PATCH net-next 0/8] complete Lynx mdio device handling

["Russell King (Oracle)" <linux@armlinux.org.uk>]

Hi,

It looks like patchwork didn't like this submission, which is no
different from any of my previous submissions:

https://patchwork.kernel.org/project/netdevbpf/list/?series=753590

It seems to have no patches associated with the series, yet it does
know that there are patches associated with the series:

https://patchwork.kernel.org/project/netdevbpf/cover/ZHoOe9K/dZuW2pOe@shell.armlinux.org.uk/
https://patchwork.kernel.org/project/netdevbpf/patch/E1q56xm-00BsuT-8I@rmk-PC.armlinux.org.uk/
https://patchwork.kernel.org/project/netdevbpf/patch/E1q56xr-00Bsua-Bg@rmk-PC.armlinux.org.uk/
https://patchwork.kernel.org/project/netdevbpf/patch/E1q56xw-00Bsug-Eb@rmk-PC.armlinux.org.uk/
... etc ...

each of which link back to the series. So there are back-links to the
series but no forward-links. Sounds like a bug in patchwork :(

Any ideas what went wrong with patchwork, and whether this is just a
one-off due to timings of emails hitting patchwork, or something more
fundamental?
