            I've filed LU-12837 to track the man pages and test case.

            Still need the llapi_changelog_start.3 and llapi_changelog_in_buf.3 man pages, and a test case for llsom_sync using CHANGELOG_FLAG_FOLLOW.

            TODO for this ticket:

            • add test case for CHANGELOG_FLAG_FOLLOW, preferably using llsom_sync since it also doesn't have a test case?
            • add man page llapi_changelog_in_buf.3
            • add man page llapi_changelog_start.3 that includes a description of the new CHANGELOG_FLAG_FOLLOW flag (unfortunately no such document exists today that could just be updated)
            • bonus points if you also add man pages for other llapi_changelog_* functions
