From 7e7de876ae9bdb1b994dee148c6dc009ce94c48e Mon Sep 17 00:00:00 2001 From: Cam Macdonell Date: Mon, 27 Aug 2012 12:12:19 -0600 Subject: ivshmem: remove redundant ioeventfd configuration setup_ioeventfds() is unnecessary and actually causes a segfault when used ioeventfd=on is used on the command-line. Since ioeventfds are handled within the memory API, it can be removed.
