Fedora 35, not fully up-to-date
I run a SiliconDust tuner that converts OTA TV to mp2, which I'm then able to play back using mplayer. An hard-wired ethernet connection is used between the tuner and the main CPU.
I notice that there are leftover kworker processes. They are mostly idle and only a few have non-zero time, and then at most only a couple of seconds.
For example, 87547 ? I 0:00 [kworker/u16:1-phy0] 87554 ? I 0:00 [kworker/7:2-events] 87555 ? I 0:00 [kworker/5:2-events] 87556 ? I 0:00 [kworker/u16:2-btrfs-endio-write] 87557 ? I 0:00 [kworker/u16:3-btrfs-delalloc] 87558 ? I 0:00 [kworker/u16:5-btrfs-endio-write] 87559 ? I 0:00 [kworker/u16:7-events_unbound] 87560 ? I 0:00 [kworker/u16:9-btrfs-freespace-write] 87561 ? I 0:00 [kworker/u16:10] 87626 ? I< 0:00 [kworker/u17:1]
The leftover processes seem to vanish when the system is suspended.
Should I be concerned? In particular, I was not aware that I had installed the btrfs filesystem.
Thanks.
