Peter Oberparleiter 28844fd512 s390/hypfs: Enable limited access during lockdown ... [ Upstream commit 3868f91044 ] When kernel lockdown is active, debugfs_locked_down() blocks access to hypfs files that register ioctl callbacks, even if the ioctl interface is not required for a function. This unnecessarily breaks userspace tools that only rely on read operations. Resolve this by registering a minimal set of file operations during lockdown, avoiding ioctl registration and preserving access for affected tooling. Note that this change restores hypfs functionality when lockdown is active from early boot (e.g. via lockdown=integrity kernel parameter), but does not apply to scenarios where lockdown is enabled dynamically while Linux is running.
