Hi, this is your Linux kernel regression tracker. Top-posting for once,
to make this easily accessible to everyone.
Miquel, Richard, Vignesh: what's up here? This patchset fixes a
regression. It's quite old, so it's not that urgent, but it looked like
nothing happened for two and a half week now. Or was progress made
somewhere?
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
P.S.: As the Linux kernel's regression tracker I'm getting a lot of
reports on my table. I can only look briefly into most of them and lack
knowledge about most of the areas they concern. I thus unfortunately
will sometimes get things wrong or miss something important. I hope
that's not the case here; if you think it is, don't hesitate to tell me
in a public reply, it's in everyone's interest to set the public record
straight.
