From 084a3c41243150aa3f97ffd442072ece59b6d9cc Mon Sep 17 00:00:00 2001 From: Michael Jeanson Date: Mon, 31 Aug 2020 11:41:38 -0400 Subject: [PATCH] fix: writeback: Drop I_DIRTY_TIME_EXPIRE (v5.9) See upstream commit: commit 5fcd57505c002efc5823a7355e21f48dd02d5a51 Author: Jan Kara 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.
