[Dovecot] More msync issues...

[Andrew Hutchings]

Sorry Doug, just tried to investigate a bit (I am not the best
programmer in the world).  Msync should be called as follows:

int msync(void *addr, size_t len, int flags);

It looks to me in your case the parameter 2 is supposed to parameter 1
and I don't know what the heck got shoved in parameter 1.  Maybe
parameter 1 was supposed to be parameter 2 without the 0x??

Regards
Andrew
