Constify local structures.
The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/)
Just my two cents but:
- You *can* use a static analysis too to find bugs or other issues.
- However, you should manually do the commits and proper commit messages to subsystems based on your findings. And I generally think that if one contributes code one should also at least smoke test changes somehow.
I don't know if I'm alone with my opinion. I just think that one should also do the analysis part and not blindly create and submit patches.
All of the patches are compile tested. And the individual patches are submitted to the relevant maintainers. The individual commit messages give a more detailed explanation of the strategy used to decide that the structure was constifiable. It seemed redundant to put that in the cover letter, which will not be committed anyway.
julia
Anyway, I'll apply the TPM change at some point. As I said they were for better. Thanks.
