Subject: mm/writeback: commit reason of WB_REASON_FORKER_THREAD mismatch name
After 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.
