The patch does not apply as is:

Even as I fixed the patch, it still does not compile, for example:
/src/qemu/block.c:1335: warning: 'struct iovec' declared inside parameter list
/src/qemu/block.c:1336: error: conflicting types for 'bdrv_aio_writev'
/src/qemu/block.h:106: error: previous declaration of 'bdrv_aio_writev' was here
/src/qemu/block.c:1425: error: invalid use of undefined type 'struct iovec'
