From fc6df808aaf00eed564e2e7fc0f246691363cd12 Mon Sep 17 00:00:00 2001 From: Wanpeng Li Date: Mon, 8 Jul 2013 16:00:15 -0700 Subject: mm/writeback: commit reason of WB_REASON_FORKER_THREAD mismatch name After commit 839a8e8660b6 ("writeback: replace custom worker pool implementation with unbound workqueue"), there is no bdi forker thread any more. However, WB_REASON_FORKER_THREAD is still used due to it is TPs userland visible and we won't be exposing exactly the same information with just a different name.
