Motivation: #8143 describes "stuck" hot file migration jobs. Analysis suggests these are not actually stuck, but just extremely slow due to the migration job's survey of the repository during initialization. Modification: An overloaded `start()` function bypasses the repository survey when the files at issue are already known. Result: The initialization time for hot file migration jobs in large repositories is vastly reduced. Closes: #8143 Patch: https://rb.dcache.org/r/14670/diff/raw/ Commit: Target: master Request: 12.0, 11.2, 11.1, 11.0, 10.2 Requires-notes: yes Requires-book: no Acked-by: Dmitry Litvintsev
