[Qemu-devel] [PULL 48/65] slirp: rename exec_list

[Samuel Thibault]

From: Marc-André Lureau <address@hidden>

This list is not only used to handle command to execute on guest
connection, it can also redirect to an arbitrary object, such as a
chardev. Let's rename the struct and the field to "guestfwd".
