Kernel stress testing coverage

2001-03-08 Thread Paul Larson
I'm looking for some advice from all of you that know and understand the Linux kernel so well. I'm not a kernel developer, but I want to do some verification work on it, namely stress testing to begin with. I'm working on putting together a suite of tests to test the linux kernels under stress l
