It's not really about what I want but more about how the interface
looks in the first place. Something like the following is simply
ugly.
int my_callback(param a, param b, param c)
{
WARN_ON(b != B);
do_something(a);
}
And @sync might be useful depending on who's waking it up, so we
either need to change the wake interface or give it an easier way to
pass those parameters as received. The callback function isn't the
right place to ignore those parameters. It simply doesn't know why
the caller is passing them in or what they mean under the
circumstances.
Thanks.
