Looks like all the unhelpful BUG() aren't gone yet :-/
This one is really not helpful, I don't even know which one of my filesystems
caused the crash :(
Why is this not remounting the filesystem read only?
Really, from a user and admin perspective, this is really not helpful.
Could someone who know more than me do a pass and eradicate those?
Btrfs cannot be a production filesystem as long as those are still around IMO.
Thanks,
Marc
