Huh, this might be one of the few examples of “don’t break userspace” not being held to by Linus and co? I’m sure stuff like this has happened before, but “don’t break userspace” has been a fairly strong guiding principle for the kernel for sometime. So seeing something like this happen is actually a bit surprising.

Though I guess it could be argued that if the removal of fTPM causes fewer bugs/issues than leaving it in place then userspace wasn’t broken. But still, it’s interesting to see regardless.
