  "message": "writeback: fix possible bdi writeback refcounting problem\n\nwb_clear_pending AFAIKS should not be called after the item has been\nput on the list, except by the worker threads. It could lead to the\nsituation where the refcount is decremented below 0 and cause lots of\nproblems.\n\nPresumably the !wb_has_dirty_io case is not a common one, so it can\nbe discovered when the thread wakes up to check?\n\nAlso add a comment in bdi_work_clear.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n",
