From de13b2ac741f52000f6de185a78cc844b7565fe5 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Sat, 26 May 2018 18:03:34 +0800 Subject: [PATCH] f2fs: fix to don't trigger writeback during recovery [ Upstream commit 64c74a7ab505ea40d1b3e5d02735ecab08ae1b14 ] - f2fs_fill_super - recover_fsync_data - recover_data - del_fsync_inode - iput - iput_final - write_inode_now - f2fs_write_inode - f2fs_balance_fs - f2fs_balance_fs_bg - sync_dirty_inodes With data_flush mount option, during recovery, in order to avoid entering above writeback flow, let's detect recovery status and do skip in f2fs_balance_fs_bg.
