Initially I also questioned making "integrity" an LSM. Perhaps it's time to reconsider. For now, it makes sense to just fix the NULL pointer dereferencing.Do we think calling panic() as "fix the NULL pointer dereferencing" ?
Not supplying "integrity" as an "lsm=" option is a user error. There are only two options - allow or deny the caller to proceed. If the user is expecting the integrity subsystem to be properly working, returning a NULL and allowing the system to boot (RFC patch version) does not make sense. Better to fail early. Mimi
