No problem. That's what review is for ;-)
BTW, unless anyone is specifically interested I don't think there
is a reason to re post the test patches before the submission request.
Certainly not for the small fixes that I requested.
I do request that you post a link to a branch with the fixed test
so that we can experiment with the kernel patches.
I've also CC'ed Matthew who may want to help with review of the test
and man page that you posted in the cover letter [1].
Thanks,
Amir.
