If OI scrub is triggered by RPC, it's often a partial OI scrub, but this may not fix the inconsistencies because this partial scrub focuses on the inconsistent mappings found by RPC, and not all inodes are scanned. This is observed on customer site.

Besides, such partial OI scrub complicates the scrub state machine, to simplify the logic and avoid hidden issues, it's better to remove the partial scrub triggered by PRC, as can avoid system hung (because inconsistent mappings are not fixed).
