A string representation of the kernel_read_file_id enumeration is
needed for displaying messages (eg. pr_info, auditing) that can be
used by multiple LSMs and the integrity subsystem. To simplify
keeping the list of strings up to date with the enumeration, this
patch defines two
This LSM enforces that kernel-loaded files (modules, firmware, etc)
must all come from the same filesystem, with the expectation that
such a filesystem is backed by a read-only device such as dm-verity
or CDROM. This allows systems that have a verified and/or unchangeable
filesystem to enforce modu

So, we gained a little overall. And while the individual drivers have a

All i2c-muxes have a parent adapter and one or many child

this was stored per child adapter, but it is only needed
