From e959c8f543e11dadf7f6923427fb3acb452a0de6 Mon Sep 17 00:00:00 2001 From: Hou Pengyang Date: Tue, 25 Apr 2017 12:45:13 +0000 Subject: f2fs: lookup extent cache first under IPU scenario If a page is cold, NOT atomit written and need_ipu now, there is a high probability that IPU should be adapted. For IPU, we try to check extent tree to get the block index first, instead of reading the dnode page, where may lead to an useless dnode IO, since no need to update the dnode index for IPU.
