mainline inclusion

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/fs?id=ba679de9c3fc511f457ea0ad8f5a22e9152fa07b



--------------------------------

Commit e8e8a0c6 ("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.
