Around a year and a half ago, I’ve asked my former company for some time to
work on an issue that was impacting the debugging capabilities in our project:
gdbserver couldn’t debug multithreaded applications running on a PowerPC32
architecture. The connection to the gdbserver was broken and it couldn’t
control the debug session anymore. Multiple people have already investigated
this problem and I had a good starting point, but we still weren’t sure in
which software component the issue lied: it could have been the toolchain, the
gdbserver, the Linux kernel or the custom patches we applied on top of the
kernel tree. We were quite far away from finding the root cause.
Especially in this particular case the effort is in debugging the problem, not doing the actual fix - which is the bug report, where he got credited for. lkml is not the place for “how I debugged this problem” - that’d be what goes into his blog. And if you look around you’ll see a lot of “how I helped solving this problem” kind of blog posts.
This change is so simple that guiding him to do it in a good way would involve fixing it yourself in the explanation - and then you’d not show the code so he can do it himself? That’s just silly. If he cares about that he came out of that with quite a bit of experience on how to handle it the next time - and he mentions he even got an (assumed to be starter friendly) other issue suggested if he wants to have code in the kernel.
From the perspective of hiring people he turned this from a “nice work debugging a problem, might be a useful candidate” to “tries getting low quality code merged for vanity reasons, let’s avoid that guy”
