Thx!
qemu_ram_writeback() doesn't return any status. How can I know that actual 
msync succeds?

Also qemu_ram_writeback() requires me to include #include "exec/ram_addr.h". 
After including it when I compile code I'm getting following error:

In file included from hw/block/nvme.c:49:
/root/sources/pmr/qemu/include/exec/ram_addr.h:23:10: fatal error: cpu.h: No 
such file or directory
   23 | #include "cpu.h"
      |          ^~~~~~~
compilation terminated.
make: *** [/root/sources/pmr/qemu/rules.mak:69: hw/block/nvme.o] Error 1

Why this is happening and what should be changed.
