    net/atm: move all compat_ioctl handling to atm/ioctl.c · 805003a4
    Arnd Bergmann authored
    We have two implementations of the compat_ioctl handling for ATM, the
    one that we have had for ages in fs/compat_ioctl.c and the one added to
    net/atm/ioctl.c by David Woodhouse. Unfortunately, both versions are
    incomplete, and in practice we use a very confusing combination of the
    For ioctl numbers that have the same identifier on 32 and 64 bit systems,
    we go directly through the compat_ioctl socket operation, for those that
    differ, we do a conversion in fs/compat_ioctl.c.
    This patch moves both variants into the vcc_compat_ioctl() function,
    while preserving the current behaviour. It also kills off the COMPATIBLE_IOCTL
    definitions that we never use here.
    Doing it this way is clearly not a good solution, but I hope it is a
    step into the right direction, so that someone is able to clean up this
    mess for real.
