commit c065e93d5a0fe16e6cfb81d61ab6f5aaee9c25a6
Author: Helge Deller <deller@xxxxxx>
Date: Tue Feb 19 21:23:59 2013 +0100
fallocate(off_t) gets redirected by glibc to fallocate64(loff_t) where
the 64bit loff_t values get splitted into two 32bit (hi/lo) values. This
patch fixes this syscall for the 32- and 64bit kernel.
