Re: [PATCH] ima: Calculate digest in ima_inode_hash() if not available

__ima_inode_hash() checks if a digest has been already calculated by

Users of ima_file_hash() and ima_inode_hash() (e.g. eBPF) might be
interested in obtaining the information without having to setup an IMA
policy so that the digest is always available at the time they call one of
those functions.

Things obviously changed, but the original use case for this interface,
as I recall, was a quick way to determine if a file had been accessed
on the system.
