Hi, this once again is your Linux kernel regression tracker speaking.

If anyone wonders: this was for v5.11-rc1.

And there are these two pages now for 19 days. What's the hold-up? Or do
you consider the changes to dangerous to merge now?
Sure, it's not a recent regression, so it might not look that urgent.
But it OTOH affects everyone that can't go back to v5.10 (the newest
Longterm kernel without the regression) -- for example if a user needs a
post-v5.10 feature or upgrades to a distro with a newer kernel.
That's why this fix (unless you considerer it to dangerous) IMHO should
be merged rather sooner than later and and not wait for the merge window
of v5.17. Another aspect against waiting for the next merge window: it
contributes to piling up a large number of changes that need to be
backported to stable and longterm kernels once v5.17-rc1 is out,
resulting in stable and longterm releases with a huge pile of changes:
