Normally this "From" line is only seen when the sender isn't the patch
author.  Any ideas what happened?

Good catch!  IMA policy rules based on LSM labels are used to
constrain which files are in policy.  Normally a single LSM label is
enough (e.g. dont_measure obj_type=auditd_log_t).  Could you include
in this patch description a use case where multiple LSM labels are
needed?

thanks,

Mimi
