So, I'm not sure if this is a kernel headers/assembly bug (as ioctl is used from there), gcc-9 bug, or the combination of the two.

This sounds like a retpoline mitigation. ** Also affects: klibc (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: klibc (Ubuntu Eoan) Importance: Undecided Status: New ** Also affects: gcc-9 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850184 Title: losetup -f broken in 2.0.6-1ubuntu2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-9/+bug/1850184/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
