The original bug is just an annoyance in my opinion and a cornercase as
well. From what I can tell it makes it impossible to get extended
attributes for any file, but only if you have a mixed i386/amd64
environment, run the amd64 kernel while having i386 e2fsprogs. The
impact of that should be
IOW, I think backing out the patch and reintroducing the original
problem is better than keeping the regression the fix introduced to
stick around.

@rolf,
I apologize for this getting released. I/we care very much about
regressions. I take full responsibility for this happening.
In the future if there is an issue in verifying a fix, changing the
verification-needed- tag to verification-failed- would
help.
We will get this addressed asap.
The "I don't give a sh.."-attitude displayed here towards a regression
is shocking. Why do I even bother to test?
The regression is apparently much more severe to obot. I can no longer
take a snapshot of my btrfs filesystem.
$ sudo btrfs sub snapshot -r /mnt/LTS/@home/
Brad, how can you set this to verified and release when that introduces
a pretty severe regression? OMG!!
