Please don't bother producing and sending me such trivial patches
unless they:
- fix a real bug (in which case they are not trivial patches anymore)
- or are part of a larger (non-trivial!) series that does some real,
substantial work on this code that tries to:
- fix existing code
- speed up existing code
- or expand upon existing code with new code
The reason I'm not applying your patch is that trivial patches with no
substance following them up have more costs than benefits:
- they lead to pointless churn:
- they take up Git space for no good reason
- they slow down bisection of real changes
- they take up (valuable!) reviewer bandwidth
- they take up maintainer bandwidth
there's literally a million pointless cleanup patches that could be
done on the kernel, and we don't want to add a million commits to the
kernel tree.
This applies for this patch but also for other future patches you
might intend to send for code that I (co-)maintain.
My advice to you is to try to raise beyond newbie patches and write
something more substantial that helps Linux:
- take a look at the many bugs on bugzilla.kernel.org and try to
analyze, reproduce or fix them
- go read kernel code, understand it and try to find real bugs.
- go test the latest kernels and find bugs in it. The fresher the
code, the more likely it is that it has bugs.
- go read kernel code and try to expand upon it
Fortunately it's not hard to contribute to the kernel: there's
literally an infinite amount of work to be done on the kernel, and I
welcome productive contributions - but churning out trivial patches
with no substantial patches following them up is not productive and in
fact they are harmful once you are not a totally fresh newbie kernel
developer anymore...
Thanks,
Ingo
