The virtio_ring.h header is used in userspace programs (ie. QEMU), too. Here we can not assume that sizeof(pointer) is the same as sizeof(long), e.g. when compiling for Windows, so the typecast in vring_init() should be done with (uintptr_t) instead of (unsigned long). This fixes a compiler warning when compiling QEMU with the mingw32 cross-compiler. Signed-off-by: Thomas Huth <thuth at
