I couldn't find a contact address in MAINTAINERS, so I've CC'd the two authors listed on top of ima_create_htable.c , as well as the first submitter of the IMA stuff I found in my LKML archive. As an aside, this computer does have (some sort of) TPM chip, but the driver is built as a module, and not loaded at this point (not a worry for me, I don't intend to use it). -- Joseph Fannin jfannin@gmail.com || jhf@columbus.rr.com
