Make the rescuer process work items one-by-one instead of slurping all matches in a single pass using a cursor. Changed from V4: Control the limit and call send_mayday() in rescuer_thread(), which makes rescuer_thread() responsible for ensuring the cursor is not left behind. v4: https://lore.kernel.org/lkml/20251125063617.671199-1-jiangshanlai@gmail.com/ Lai Jiangshan (3): workqueue: Refactor send_mayday() to take pwq directly workqueue: Process rescuer work items one-by-one using a cursor workqueue: Process extra works in rescuer on memory pressure kernel/workqueue.c | 119 ++++++++++++++++++++++++++++++++++----------- 1 file changed, 91 insertions(+), 28 deletions(-) -- 2.19.1.6.gb485710b
