Linus Torvalds f10f0481a5 A fix for a bug with restartable sequences and KVM. KVM's handling ... 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. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmFLPYgUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroNCowf6A9pTuDspCC2IRICfQnHj/Q/Xc7HH UmwYo26GctfYaq9AyIAGzcRx3iOEGjb9fZVJ6mzPUGIygio9ZyuiPHogf7lMAb+x 39ts5uSOp+N+8e0fvX578WFfmG5hQa4Tp9W3T2Y5KsVgK2Nf8F08DckzIgD8cbkN NQKTRIi8AYgb20y3NFZjzsPRxF8850QK7xVCI+LBjryyWpEGT5ZsthrYUeexiJPz XN+VOYJen5GXVBCar2JbA7EVSrMZbKSy+M3fJ1vuW5dZHySaiu69JXJHop71jTnJ 5BGue917MfH6RTDzIFFUcg7NmwcuXHpw4dsFeiyExYFNw1uWWQpk0efC1g== =/xlE -----END PGP SIGNATURE----- Merge tag 'for-linus-rseq' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull rseq fixes from Paolo Bonzini: "A fix for a bug with restartable sequences and KVM.
