However, backporting it won't be that easy as it was part of a patch set. Before this patch, users of the TPM driver could only read the SHA1 PCR bank. The IMA patch needs to read also other PCR banks. > NOTE: The patch will not be queued to stable trees until it is upstream. > > How should we proceed with this patch? This question should be for Jarkko (added in CC), as some patches for the TPM driver must be backported to apply the IMA patch.
