An arch should select this symbol if it does not keep an internal kernelstate for kernel objects such as inodes, but instead relies on somethingelse (e.g. the host kernel for an UML kernel).This is used to disable Landlock for UML, correct?
Yes
I wonder if it could be more specific: "ephemeral states" is a very broad term.
How about something like ARCH_OWN_INODES ?
Sounds good. We may need add new ones (e.g. for network socket, UID, etc.) in the future though.
Because UML is the exception here, it would be more convenient to keep the inverted semantic. What about ARCH_NO_OWN_INODES or ARCH_EPHEMERAL_INODES?
