Changelog: v3 - > v4: * add Tejun's Reviewed-by * explicitly point to the TPs rather than saying "somewhat" visible
After commit 839a8e86("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.
