mainline inclusion from mainline-next-20240508 commit ba679de9c3fc511f457ea0ad8f5a22e9152fa07b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9NOHO
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/f...
--------------------------------
Commit e8e8a0c6c9bfc ("writeback: move nr_pages == 0 logic to one location") removed parameter nr_pages of __wakeup_flusher_threads_bdi and we try to writeback all dirty pages in __wakeup_flusher_threads_bdi now. Just correct stale comment.
