Hi All,

I have a kernel module which has functions which take a lot of time in
execution. I am curious to know how can I profile it, and find out the
functions taking most of the time.

I saw Oprofile, but it seems that I will have to build the whole kernel,
and also that it will be difficult to profile my module through it.

Any trick or tool will do.

Thanks a lot, I will have a look at it and see if it helps.
