    caif: reduce stack size with KASAN · ce628966
    Arnd Bergmann authored
    When CONFIG_KASAN is set, we can use relatively large amounts of kernel
    stack space:
    
    net/caif/cfctrl.c:555:1: warning: the frame size of 1600 bytes is larger than 1280 bytes [-Wframe-larger-than=]
    
    This adds convenience wrappers around cfpkt_extr_head(), which is responsible
    for most of the stack growth. With those wrapper functions, gcc apparently
    starts reusing the stack slots for each instance, thus avoiding the
    problem.
