binfmt: replace deprecated strncpy strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. There is a _nearly_ identical implementation of fill_psinfo present in binfmt_elf.c -- except that one uses get_task_comm over strncpy().
