From 94dac22e72e891b16e8e8abbdb6df10f322d20e0 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Thu, 17 Apr 2014 10:51:05 +0800 Subject: [PATCH] f2fs: introduce raw_nat_from_node_info() to simplfy codes This patch introduce raw_nat_from_node_info() to simplfy some codes, and also use exist function node_info_from_raw_nat() to do the same job.
