Hello everyone,
If someone make some modifications to kernel code and want to know how much
overead those modifications has caused, what are the benchmarks that one
should use to calculate the overhead of the added code.
please cc the reply to me.
Thanks a lot.

it really depends on what area of the kernel you're changing.. there's
no "golden" benchmark that tests the entire kernel and gives one nice
answer... there are however a lot of smaller benchmarks that test a
portion of the kernel....
Well that would very much depend on what you're changing. For example,
if it is a file system modification, then use file system benchmarks.
However, those same benchmarks would not be appropriate for changes in
the network stack. A pre-written benchmark may not even exist. You
should use your knowledge of what you are changing to choose an
appropriate benchmark that will stress that part of the kernel.

Or, as is often the case, write a benchmark app yourself to test the
specific thing you've changed.

There are a lot of benchmarks out there.
E.g., some are listed at
http://lbs.sourceforge.net/
and
http://lse.sourceforge.net/benchmarks/
just depends on what you want/need, like others have said.
