Btw, it seems to me that checkpatch.pl returns some false positives
here. See:

    ERROR: spaces required around that '&' (ctx:VxV)                                                                                                                            
    #72: FILE: qga/commands-win32.c:711:
    +        if (GetDiskFreeSpaceEx(mnt_point, 0, (PULARGE_INTEGER)&fs->size,
                                                                ^

    ERROR: spaces required around that '&' (ctx:VxV)
    #73: FILE: qga/commands-win32.c:712:
    +                (PULARGE_INTEGER)&fs->free) != 0) {
                                    ^

Seems that & is mistakenly interpreted as bitwise-AND operator. 
Or am I expected to format that as

  ..., (PULARGE_INTEGER) & fs->size, ...

because that looks... weird.


Also, checkpatch.pl itself suggest to look into MAINTAINERS to find out
whom to report false positives, but there is no maintainer there. :)
