-Subject: [PATCH] replace struct ucontext with ucontext_t type
-
-The ucontext_t type had a tag struct ucontext until now
-but newer glibc will drop it so we need to adjust and use
-the exposed type instead

-virtio-gpu: fix information leak in capset get dispatch
-
-In virgl_cmd_get_capset function, it uses g_malloc to allocate
-a response struct to the guest. As the 'resp'struct hasn't been full
-initialized it will lead the 'resp->padding' field to the guest.
-Use g_malloc0 to avoid this.
