Extern declarations in sysctl.c should be moved to their own header file, and then include them in relavant .c files. Move print_fatal_signals extern declaration to linux/signal.h Signed-off-by: Dave Young <hidave.darkstar@gmail.com> Cc: Oleg Nesterov <oleg@redhat.com> Cc: Roland McGrath <roland@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
