From 7c4abcbeccdd286e7d71b3e8f9fefad84112e54c Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Thu, 18 Aug 2016 17:46:14 +0800 Subject: [PATCH] f2fs: set dirty state for filesystem only when updating meta data We don't guarantee integrity of user data after checkpoint, since we only guarantee meta data integrity for data consistency of filesystem. Due to above reason, we only need to set fs as dirty when meta data is updated, so that we can skip writing checkpoint in some case of non-meta data is updated.
