Kuan-Wei Chiu 1fcce6b8a7 bcachefs: remove heap-related macros and switch to generic min_heap
Drop the heap-related macros from bcachefs and replacing them with the
generic min_heap implementation from include/linux.  By doing so, code
readability is improved by using functions instead of macros.  Moreover,
the min_heap implementation in include/linux adopts a bottom-up variation
compared to the textbook version currently used in bcachefs.  This
bottom-up variation allows for approximately 50% reduction in the number
of comparison operations during heap siftdown, without changing the number
of swaps, thus making it more efficient.
