Maybe the relation isn't immediately obvious from code inspection alone,
nonetheless it demonstrably is there. That commit is what introduced
the described regression. Apparently, it's only present with an amd64
kernel and 32-bit userspace.

Bug description:
I run an amd64 kernel on trusty. The e2fsprogs package was still the
32 bit i386 variety. This lead to the following situation (for
essentially all files on a btrfs partition).
$ lsattr
/lib/modules/3.13.0-95-generic/kernel/drivers/staging/lustre/lustre/ptlrpc/ptlrpc.ko
lsattr: Inappropriate ioctl for device While reading flags on
/lib/modules/3.13.0-95-generic/kernel/drivers/staging/lustre/lustre/ptlrpc/ptlrpc.ko
The problem was resolved by installing e2fsprogs:amd64.
https://patchwork.kernel.org/patch/7517361/ might be related.
