From 3734bb9068d4b66fa76b0e13a027b1a8497ae27f Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 9 Jan 2014 10:43:28 +0800 Subject: Add and use 'string_to_fraction()' helper converter function This matches the pattern of unit conversion, and will allow us to remove all the code that uses the old complex "CHANGED()" macro that tries to remove units or percent signs.
