In the last decade, nobody's tried to fix it in mainline that I know of.
As I said, some vendors have tried to fix it in their NAS products,

Arnd found it for me.

They've done a perfect job of making the source available while making it
utterly dreadful to extract anything useful from.

Wow, I thought RedHat was the only open-source vendor that tries to send
out a super big patch to make life of every other guys miserable.
And I'm definitely wrong now.
It's full of gratuitous whitespace changes to files that definitely
aren't used (arch/alpha? really?) and they've stripped out a lot of
comments that they didn't need to touch.
Forward porting a patch from 10 years ago wouldn't be easy, even if
they hadn't tried very hard to obfuscate their patch. I don't think
this will be a fruitful line of inquiry.
Yeah, I believe it's not worthy now.
I'll make btrfs to try its best to reject the fs instead.
Thanks,
