[PATCH net 2/4] virtio-net: remove redundant truesize check with PAGE_SIZE

The truesize is guaranteed not to exceed PAGE_SIZE in get_mergeable_buf_len(). It is saved in mergeable context, which is not changeable by the host side, so the check in receive path is quite redundant. Signed-off-by: Bui Quang Minh --- drivers/net/virtio_net.c | 7 +++ 1 file changed, 3 in
