So do you have a plan to fix it?

I don't think it'll be possible to do drastic changes in the
VFS for 2.6.33, and it seems preserving the current semantics
would need that.

Delaying a fix to after 2.6.33 is not an option imho.

It hits everyone with LOCKDEP enabled who uses mmap over NFS.
That's new in 2.6.33, previously LOCKDEP didn't diagnose this.

I'll keep using my patch, but I suppose once we're going more
towards a release you'll get more reports of this.
