Any idea what's going on, what causes it, and/or how I can fix it?

That doesn't seem to be true in practice. In the test below I mmap a
1080K file (this is a multiple of 4K but not a multiple of 64K). The
first byte after the end of the file isn't readable.
$ cat mmaptest.c
#include
#include
#incl
I have an application that wants to use mmap() to read a file, but
only if it can guarantee that this will leave one or more zero bytes
after the end of the contents of the file in memory:
if ((filesize & (pagesize - 1) != 0)
use_mmap();
else
use_read();
How do I get the appropriate p
