Workqueues and Worker thread name

Hi,

I am a little new to this area, so seeking expert advice.

I have created "delayed works" using "INIT_DELAYED_WORK" for each core
on my system and a corresponding work_queues using
"create_freezable_workqueue".
Now what I have some work getting scheduled on this queues. What I
observe is that top command shows CPU being taken by kernel threads as
below-
 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  #C WCHAN     COMMAND
101 root      20   0     0    0    0 R  9.6  0.0  63:16.29  6
worker_th [kworker/6:1]
  104 root      20   0     0    0    0 S  9.6  0.0  70:53.11  3

worker_th [kworker/10:1]
  102 root      20   0     0    0    0 S  9.0  0.0  61:08.43  5
worker_th [kworker/5:1]
   96 root      20   0     0    0    0 S  8.6  0.0  50:55.86 11
worker_th [kworker/11:1]


How, do I know if this is for the work that I have created and its
taking that much CPU. Also, while creating the work_queues I have a
name to them. How to relate that name here in top.

Any help will be highly appreciated.

Thanks,
Prashant
