Switch the DO_ONCE() macro from the deprecated jump label API to the new
one.  The new one is more readable, and for DO_ONCE() it also makes the
generated code more icache-friendly: now the one-time initialization
code is placed out-of-line at the jump target, rather than at the inline
fallthrough case.

Thanks!

Great!  Who though is the maintainer for this code?  It seems it was originally
taken by David Miller through the networking tree.  David, are you taking
further patches to the "once" functions, or should I be trying to get this into
-mm, or somewhere else?

Ping.

Given original code was accepted against net-next tree as major users of
the api are networking related anyway, it should be fine here as well to
route through this tree. Maybe resend the patch with a [PATCH net-next]
in the subject line (as usually done) to make the targeted tree more clear.
