If your solution to a stubborn susbsystem is to go around them by convincing another, potentially unrelated subsystem, to merge the patch then I firmly believe you are doing it wrong. >> > It's _much_ simpler and provides a generic mechanism to >> > get the entire patch applied to send a single patch to the >> > top level subsystem maintainer. >> >> I understand it is simpler for you, but it is more difficult for everyone else. > > Not true. I think we are at the agree to disagree stage. The way you have structured this patch it makes it easier for you to submit, but makes it potentially more difficult for me (likely other LSM maintainers too), the -next folks, and Linus. > It's simply a matter of merge resolution being pushed down > where and when necessary. > > See changes like the additions of the SPDX license tags. Please don't even try to suggest that this trivial patch you are proposing is even remotely as significant as the SPDX change. There are always going to be exceptions to every rule, and with each exception there needs to be a solid reason behind the change. The SPDX change had a legitimate reason (legal concern) for doing it the way it was done; this patch isn't close to that level of concern. >> Further, where the LSMs are concerned, there is no "top level >> subsystem maintainer" anymore.

I'll put together a patch for selinux/next as soon as the merge window closes. I'll let the other LSMs do as they see fit. As I said previously, I believe the only other LSM that sends directly to Linux is AppArmor. -- paul moore www.paul-moore.com
