of TIF_NOTIFY_RESUME, e.g. for task migration, clears the flag without informing rseq and leads to stale data in userspace's rseq struct. I'm sending this as a separate pull request since it's not code that I usually touch. In particular, patch 2 ("entry: rseq: Call rseq_handle_notify_resume() in tracehook_notify_resume()") is just a cleanup to try and make future bugs less likely. If you prefer this to be sent via Thomas and only in 5.16, please speak up.
