[LU-16413] T10PI is broken for CentOS 8.x

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.16.0, Lustre 2.15.3
• Severity: 3
• Assignee: Dongyang Li
• Reporter: Dongyang Li

Description

The T10PI block integrity patches for lustre server kernel is broken, the bio_integrity_prep_fn interface is removed.

As a result the autoconf feature test macro HAVE_BIO_INTEGRITY_PREP_FN was not defined, and the custom block integrity generate/verify was never enabled for CentOS 8.x

The current block integrity generate/verify functions also require changes to be able to work on CentOS 8.x kernels.

I spent some time last week trying to get dm-integrity working, and hopefully we can have some smoke testing cases e.g. sanity-integrity. But seems it's intended to work with dm-crypt,

the block device queue won't have integrity flags set, so not really useful for us.
