Introduce distinct struct balance_callback instead of performing function pointer casting which will trip CFI. Avoids warnings as found by Clang's future -Wcast-function-type-strict option:
In file included from kernel/sched/core.c:84: kernel/sched/sched.h:1755:15: warning: cast from 'void (*)(struct rq *)' to 'void (*)(struct callback_head *)' converts to incompatible function type [-Wcast-function-type-strict] head->func = (void (*)(struct callback_head *))func; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
No binary differences result from this change.
This patch is a cleanup based on Brad Spengler/PaX Team's modifications to sched code in their last public patch of grsecurity/PaX based on my understanding of the code. Changes or omissions from the original code are mine and don't reflect the original grsecurity/PaX code.
