From b4d34037329f46ed818d3b0a6e1e23b9c8721f79 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Thu, 20 Aug 2015 00:49:48 +0300 Subject: [PATCH] virtio_ballon: change stub of release_pages_by_pfn and rename it to release_pages_balloon. The function originally takes arrays of pfns and now it takes pointer to struct virtio_ballon. This change is necessary to conditionally call adjust_managed_page_count in the next patch.
