He built a kernel that was based on applying a source code patch that I put out for review, see https://reviews.freebsd.org/D23376 . There is no snaphot. None of the code changes are part of FreeBSD at this point. Even if the techniques involved are all deemed okay as they are, the source code is going to need a round of conversion to style(9) criteria to be acceptable for check-in. (I've seen references to style(9) but am not familiar with the content and did not add that to my burden back when I was trying to figure out how to avoid this threads-stuck-sleeping issue and, before that, investigating avoiding the usefdt mode failures, both being PowerMac-context problems. I'd be amazed if how I coded happened to fit an unknown-to-me coding standard.) I've been running with the changes since 2019-May or so, building and using a few versions of FreeBSD since then. My current context is head -r356426 based (so older than Francis Little's head -r357172 context). === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)home | help
