Thanks for fixing this up! I think it would be easier for reviewers to validate your edition if you:
Then we can squash+merge once reviewed. Do you mind reforming this PR that way? (I think you could also force push to this branch if you're comfortable doing that, otherwise a new PR is fine). Thanks for the patch! |
@nickdesaulniers I created the new PR as you said: #93622 |
New pull request for #89443
Adds the missing pthread_rwlockattr_getkind_np / pthread_rwlockattr_setkind_np functions and tests respecitvely.
I made sure everything is committed this time.
