| Doc Text: |
Previously, the cache_restore utility passed incorrect arguments to a function. Additionally, it missed a call to flush dirty bits when version 2 metadata of the cache was used. As a consequence, the utility corrupted the cache metadata. With this update, cache_restore now handles the arguments correctly and adds the missing call. As a result, the utility no longer corrupts version 2 metadata.
