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.
I don't know why you think they are "leftover". They are kernel processes that are started internally as necessary.
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]
On my computer right now: $ ps auxw | grep kworker | wc -l 84
Should I be concerned? In particular, I was not aware that I had installed the btrfs filesystem.
btrfs is the default now, but if you aren't using it, I don't know why those would be there. But in general, kworker processes are normal.
