Subject: fix mem_write() return value
From: Frederik Deweerdt <deweerdt@xxxxxxx>
At the beginning of the routine, "copied" is set to 0, but it is no good
because in lines 805 and 812 it is set to other values. Finally, the
routine returns as if it copied 12 (=ENOMEM) bytes less than it actually
did.
