From: Jiri Slaby <[email protected]> commit 8e742aa79780b13cd300a42198c1a4cea9c89905 upstream.
After the commit below, truncate() on x86 32bit uses ksys_ftruncate(). But ksys_ftruncate() truncates the offset to unsigned long. Switch the type of offset to loff_t which is what do_sys_ftruncate() expects.
