Why? Do you have real use cases that are broken by this? I understand
this is a problem, but I'm curious on how this satisfies the stable
Also, note that this isn't a regression; it's been broken forever and
apparently no one noticed. IMO that raises the bar a bit (but not
impossibly so) for -stable.
Anyway, if we decide to do this, you'll also want to include the git
hash and applicable kernel versions, per Option 2 .
