This regression is fixedi (or better worked around) in your git by the

This regression does still need to be listed for 2.6.33-rc8-git.

Americo is right that the warning goes away if I apply those patches from Eric,
but they look like more than we'd be adding into 2.6.33 at this stage ...
and bootup of latest git plus those patches gave me 71 messages of the form
BUG: key fxxxxxxx not in .data!

Which probably means one or two more spots that need annotation.

2.6.33 is out so these are targeted for 2.6.34...

sending it in.

Rather the second one, i.e. it fixes it for me. The patch is named

sysfs-cache-the-last-sysfs_dirent-to-improve-readdir-scalability-v2.patch

and is "stuck" in Greg's tree. Judging by the quilt series¹, the patch
is slated for submission after 2.6.33. This late in the game for .32,
I'm guessing maybe a stable backport after .33 is out?

Do you mean "fixed" as "the fix is in the Linus' tree" or "fixed" as "the
