That is perfectly fine as a status update for me (I track a lot of
regression and it's easy to miss updated patches, discussion in other
places, and things like that).

Could you maybe send a reminder to the maintainer that this is a fix for
regression that is bothering people and needs to be handled with high
priority? Feel free to tell them the Linux kernel regression tracker is
pestering you because things are taken so long. :-D

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
