From a912b54d3aaa011266dc266e3694f782f27233cf Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Wed, 10 May 2017 11:18:25 -0700 Subject: f2fs: split bio cache Split DATA/NODE type bio cache according to different temperature, so write IOs with the same temperature can be merged in corresponding bio cache as much as possible, otherwise, different temperature write IOs submitting into one bio cache will always cause split of bio.
