I feel sorry if that's what you perceived. But I'm just submitting
test results rather than complaining. I should actually be glad if my
test system catches more bugs. ;-) And there is no way for me to sit
back - I'm actually overloaded. Yesterday I wrote 63 emails, which is
one per 10 minutes _assuming_ I'm working 8hours. You can imagine the
works required behind all these emails.

We tried hard to build the test infrastructure for the good of Linux
community. And if you like, I'd be happy to add your git tree to our
test pool - currently it already includes 300+ kernel git trees from
various developers. It'd feel more at home to find bugs in one's own
tree, rather than in the maintainers'. :-)

Thanks,
Fengguang
