Descripción
In the Linux kernel, the following vulnerability has been resolved: io_uring/napi: cap busy_poll_to 10 msec Currently there-s no cap on the maximum amount of time that napi is allowed to poll if no events are found, which can lead to kernel complaints on a task being stuck as there-s no conditional rescheduling done within that loop. Just cap it to 10 msec in total, that-s already way above any kind of sane value that will reap any benefits, yet low enough that it-s nowhere near being able to trigger preemption complaints.
