Subject: [Qemu-devel] [PATCH 4/4] virtio: Plug memleak by freeing vdev
Date: Wed, 27 Jul 2011 14:00:32 +0530 [thread overview]
Message-ID: <0139341db2e3b0402f2396b78daf535fe182044e.1311755243.git.amit.shah@redhat.com> (raw)
In-Reply-To: <cover.1311755243.git.amit.shah@redhat.com>
In-Reply-To: <cover.1311755243.git.amit.shah@redhat.com>
virtio_common_init() allocates RAM for the vdev struct (and any
additional memory, depending on the size passed to the function). This
memory wasn't being freed until now.
