This needs to be "1", not sizeof(bool), because vmstate_info_bool writes
a single byte.  I'll fix this and queue the patch (removing Amit's
reviewed-by since it's effectively a different change).

Eeks, yes.

This patch was merged in the meantime, so Cao Jin, please post a
revert and a fix, thanks!

Before I send the fix, I did a quick test on linux as following:

#include <stdio.h>
#include <stdbool.h>

int main()
{
    printf("bool size = %d\n", sizeof(bool));
}


then:
./a.out
bool size = 1

and there is mptsas.c #include "qemu/osdep.h", osdep.h #include <stdbool.h>

So, am I missing something?
