• f8c269d72   btrfs: cleanup 64bit/32bit divs, compile time constants ... Browse Code »

  Switch to div_u64 if the divisor is a numeric constant or sum of
  sizeof()s. We can remove a few instances of do_div that has the hidden
  semtantics of changing the 1st argument.

  Small power-of-two divisors are converted to bitshifts, large values are
  kept intact for clarity.

• 3fed40cc9   Btrfs: cleanup duplicated division functions ... Browse Code »

  div_factor{_fine} has been implemented for two times, cleanup it.
  And I move them into a independent file named math.h because they are
  common math functions.
