That external piece of documentation would be part of the Linux man-pages
project, maintained by Michael Kerrisk. I have submitted a few revisions
of the rseq(2) man page, but have been waiting for Michael to reply for more

I'm thinking about hosting a rseq(2) man-page into my librseq project, would
that make sense ?

librseq is currently a development branch in my own repository for now. It still
needs to be tweaked to adapt to the various changes that went into the glibc rseq
