'recovery_disabled' logic is complex and confusing, originally intended to preserve raid in extreme scenarios. It was used in following cases: - When sync fails and setting badblocks also fails, kick out non-In_sync rdev and block spare rdev from joining to preserve raid [1] - When last backup is unavailable, prevent repeated add-remove of spares triggering recovery [2] The original issues are now resolved: - Error handlers in all raid types prevent last rdev from being kicked out - Disks with failed recovery are marked Faulty and can't re-join Therefore, remove 'recovery_disabled' as it's no longer needed.
