Description Neal Gompa 2021-12-12 18:55:03 UTC 
Description of problem:
To support downstream work by the CentOS Hyperscale SIG, it would be appreciated if CONFIG_CRYPTO_BLAKE2B=m could be set in the RHEL kernel configuration.

In particular, this would help us with supporting Btrfs downstream in the CentOS Stream 9 Hyperscale variant in our kernel and working with the CentOS Kmods SIG to support it as a third-party kernel module package built by them.

Version-Release number of selected component (if applicable):
5.14.0-29.el9

MR for CKI for ARK proposed: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1524
Comment 4 Peter Georg 2021-12-14 18:24:47 UTC 
Just a short comment to confirm that the Kmods SIG would very much appreciate this change (hence Jonathan and myself added to CC).
Comment 6 Simo Sorce 2021-12-16 01:34:31 UTC 
Blake2b would be disabled in FIPS mode so there should be no problem.
