Hello,

I didn't find a more suitable mail to respond to ...

I still experience a problem with the patch that got
adad556efcdd42a1d9e060cbe5f6161cccf1fa28 in v5.16-rc1. I saw there are
two commit fixing this one (

	cad439fc040e crypto: api - Do not create test larvals if manager is disabled
	e42dff467ee6 crypto: api - Export crypto_boot_test_finished

) but I still encounter the following on 2f47a9a4dfa3:
