From eae02feb58064eee5ce15a9f6bdffd107c47da05 Mon Sep 17 00:00:00 2001

Subject: [PATCH 07/10] fix: writeback: Drop I_DIRTY_TIME_EXPIRE (v5.9)
See upstream commit:
commit 5fcd57505c002efc5823a7355e21f48dd02d5a51
Author: Jan Kara <jack@suse.cz>
Date: Fri May 29 16:24:43 2020 +0200
writeback: Drop I_DIRTY_TIME_EXPIRE
The only use of I_DIRTY_TIME_EXPIRE is to detect in
__writeback_single_inode() that inode got there because flush worker
decided it's time to writeback the dirty inode time stamps (either
because we are syncing or because of age). However we can detect this
directly in __writeback_single_inode() and there's no need for the
strange propagation with I_DIRTY_TIME_EXPIRE flag.
