RE: [Fault-injection-developer] Need for benchmarking

[Lynch, R. <rus...@in...>]

Does LTP contain a benchmarking tool?  We could definitely=20
run it to make sure we didn't accidentally break something=20
else in the kernel.

BTW, do not overlook using STP on OSDL as a testing tool.
It's easy to use and there are a bunch of machines waiting
to be utilized.
