[Qemu-trivial] [PULL 18/22] replace functions which are only available i


From: Michael Tokarev
Subject: [Qemu-trivial] [PULL 18/22] replace functions which are only available in glib-2.24
Date: Sun, 20 May 2018 09:15:04 +0300

From: Olaf Hering <address@hidden>

Currently the minimal supported version of glib is 2.22.
Since testing is done with a glib that claims to be 2.22, but in fact
has APIs from newer version of glib, this bug was not caught during
submit of the patch referenced below.

Replace g_realloc_n, which is available only since 2.24, with g_renew.

Fixes commit 418026ca43 ("util: Introduce vfio helpers")
