Subject: Re: [PATCH for 5.4 0/3] Restartable Sequences Fixes

Hi Thomas,

I thought those rseq fixes posted in September were in the -tip tree, but it
seems that they never made it to mainline.

Now Shuah Khan noticed the issue with gettid() compatibility with glibc
2.30+. This series contained that fix.

Should I re-post it, or is this series on track to get into mainline
at some point ?

Thanks,

Mathieu
