The mailing list doesn't seem to like my email configuration, possibly because I use DMARC to make it difficult for unapproved servers to send mail on my behalf. I'm not going to go more than a few hours out of my way to use an archaic code review process.

immibis · 2016-04-27T08:40:05Z

@Zenexer Then this change will never be accepted.

Zenexer · 2016-05-07T02:06:29Z

@immibis That's fine; I can apply the patch myself. I've done my duty and made it available to the public via industry-standard methods. If the Linux team doesn't want patches from the next generation of programmers, who use GitHub rather than mailing lists, that's not my problem.

@ancaemanuel if you don't want to accept a pull request, you should close it on your own.

@hron84 ancaemanuel is a contributor, not a team member.

@Zenexer I missed the title, I thought he is a team member. Anyway, this is not a right way to handle issues.
