Hi,
I added a network event trace thus:
echo 1 /sys/kernel/debug/tracing/events/net/net_dev_xmit/enable
Afterwards I see many lines with net_dev_xmit in /sys/kernel/debug/tracing.
Now, looking in the source code, I see that there are two calls to
trace_net_dev_xmit() in

system calls is coming from User space/Land, there will be context switch
from user to kernel space happens. I think kernel main thread serving those
system calls.

No. Large parts of the kernel run in kernel mode, but using the 'struct task'
