Thanks!
As before, I'll be commenting the patches as I'll be seeing any issues.

In fact, the check for retval < 0 instead of retval == -1 is not a fix.
According with
mmap man pages:
RETURN VALUE
On success, mmap() returns a pointer to the mapped area. On
error, the value MAP_FAILED (that is, (void *) -1) is returned, and errno
is set appropriately. On success, munmap() returns 0, on
failure -1, and errno is set (probably to EINVAL).
The change is not wrong, as -1 is lower than 0, but using -1 is more compliant
with
libc. So, I'll be applying just the CodingStyle fixes on it.
Cheers,
mauro
