    Description

      The "lfs mirror resync" code is using its own implementation of data copying instead of migrate_copy_data(), which means that bug fixes and improvements to the data copying code (eg. bandwidth limit, stats reporting, buffer sizing, DIO usage, etc.) need to be implemented in two places.

      It would be better to have a single function to copy file data shared between the different operations.
