[Qemu-devel] [PATCH] linux-user: fix realloc size of target_fd_trans.


From: Laurent Vivier
Subject: [Qemu-devel] [PATCH] linux-user: fix realloc size of target_fd_trans.
Date: Mon, 18 Jan 2016 23:50:45 +0100

target_fd_trans is an array of "TargetFdTrans *": compute size
accordingly. Use g_renew() as proposed by Paolo.
