Is this something you're willing to merge directly please?

Done.

That said:

-K:     phylink
+K:     phylink\.h|struct\s+phylink|\.phylink|>phylink_|phylink_(autoneg|clear|connect|create|destroy|disconnect|ethtool|helper|mac|mii|of|set|start|stop|test|validate)

That's a very awkward pattern. I wonder if there could be better ways
to express this (ie "only apply this pattern to these files" kind of
thing)

Yes, it's extremely awkward - I spent much of the morning with perl
testing it out on the drivers/ subtree.

There are a lot of phylink_<foo> in the kernel.
Are those really the only uses you want to watch?

Hi Joe

I think Rusells intention here is to match on MAC drivers which make
use of the phylink API exported to them.

SFF/SFP/SFP+ MODULE SUPPORT
M:      Russell King [off-list ref]
L:      netdev@vger.kernel.org
S:      Maintained
F:      drivers/net/phy/phylink.c
F:      drivers/net/phy/sfp*
F:      include/linux/phylink.h
F:      include/linux/sfp.h
K:      phylink

$ git grep -P -oh 'phylink_\w+'| sort | uniq -c

Try that again, but skip files matched by the F: clauses.

I suspect the matches you get then more closely approximates the K:
Russell is suggesting.
