How about something like the following. I chose to wrap the call to
do_mmap_pgoff() instead of making a special ->pre_mmap(), since that
seems more consistent with the way we handle ->read() and ->write().
I also left sys_uselib() and do_execve() to rely on revalidate at
open(), since executables and libraries really are not ever expected to
change while open.
Cheers
Trond
