Re: [Ksummit-discuss] kselftest - What's in 3.17 and plans for 3.18 and beyond

Hello,

I'm also interested in the selftests, especially its
framework (top-level script).

Instead of running the selftests, can we build the testcases and
install it as a tool? I think running tests on the tree is not a
good idea...
Also, as I said in above mail, I'd like to suggest to add at least
log management and statistics to the test. Those are good to automate
regression tests. :)
