[PATCH 6/7] fs/writeback: correct comment of __wakeup_flusher_threads_bdi
Posted by Kemeng Shi 2 years ago
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.
