From 60dcedc9972d136fab1600c919dd32080bcc26f7 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Wed, 2 Nov 2016 20:43:21 +0800 Subject: f2fs: record inode updating status correctly We should record updating status of inode only for living inode, for those unlinked inode it needs to clear its ino cache, otherwise after the ino was been reused, it will cause unneeded node page writing during ->fsync.
