xfs: support a crc verification only log record pass
Log recovery torn write detection uses CRC verification over a range of the active log to identify torn writes. Since the generic log recovery pass code implements a superset of the functionality required for CRC verification, it can be easily modified to support a CRC verification only pass. Create a new CRC pass type and update the log record processing helper to skip everything beyond CRC verification when in this mode. This pass will be invoked in subsequent patches to implement torn write detection. Signed-off-by:Brian Foster <bfoster@redhat.com> Reviewed-by:
