Description msiddiqu 2021-02-17 06:18:09 UTC
Grant mapping operations often occur in batch hypercalls, where a
number of operations are done in a single hypercall, the success or
failure of each one reported to the backend driver, and the backend
driver then loops over the results, performing follow-up actions based
on the success or failure of each operation.
