Hi,

Please find the rseq-enablement patchset for comments in this series.

This patch series is based on glibc master branch at commit
a059f9505b tunables: report sbrk() failure

Since the last post, I moved all entries from Changelog.old/*
to the commit messages.

Thanks for the feedback!

Mathieu

The syscall table patches have since been merged.

I think this is too late for the 2.31 release now (unless Siddhesh
disagrees). 8-(

We should try to get the patches ready for merging in February, though.

Thanks,
Florian

Very good! I've rebased my work on top of master.

I will repost the updated patchset right away anyway following your
comments.

Thanks for the feedback!
