Hi Linus,

The Integrity pull request for v5.15 contains only IMA changes:

- Limit the allowed hash algorithms when writing security.ima xattrs or
verifying them, based on the IMA policy and the configured hash
algorithms.

- Return the calculated "critical data" measurement hash and size to
avoid code duplication.  (Preparatory change for a proposed LSM.)

[Stephen Rothwell addressed a merge conflict between the new device
mapper "critical data" measurements (drivers/md/dm-ima.c) and extending
the "critical data" measurement function.]

- and a single patch to address a compiler warning.

thanks,

Mimi
