From 5fe457430e554a2f5188f13c1a2e36ad845640c5 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Sat, 7 Jan 2017 18:50:26 +0800 Subject: f2fs: introduce FI_ATOMIC_COMMIT This patch introduces a new flag to indicate inode status of doing atomic write committing, so that, we can keep atomic write status for inode during atomic committing, then we can skip GCing pages of atomic write inode, that avoids random GCed datas being mixed with current transaction, so isolation of transaction can be kept.
