Subject: [PATCH] vhost: fix guest pages memory leak
[ upstream commit 29c7c2fdaa4e88eebee6e3abaa15858d9616b1aa ]
This patch fixes a memory leak.
virtio_net::guest_pages is allocated in vhost_setup_mem_table(),
reallocated in add_one_guest_page(), but never freed.
Fixes: e246896178e6 ("vhost: get guest/host physical address mappings")
