Excessive kworker entries in process status table when system is idle.

ayush.gupta — Sun, 21 Apr 2013 22:13:43 +0000

When I list the processes executing on my system it displays many kworker/ processes with interruptible sleep (waiting for an event to complete) , an unknown value of tty and many different pids (even if my system is idle).
Also when I execute “top” it does not display any entry of kworker.
I am using fedora 16_64bit and 3.4.9-1.fc16.x86_64 kernel.
Can anyone please explain what kworker is/does? Why are there so many entries for kworker processes in the process status table?
