Comment From: cherrymui

debug/elf, hash/maphash, os, reflect, runtime, runtime/trace, sync, and testing/synctest LGTM.

Comment From: cherrymui

@findleyr mentioned offline that go/* packages look good.

Comment From: aclements

All new APIs LGTM, with a few minor issues I'm tracking:

  • [x] Possibly making the zero value of net/http.CrossOriginProtection usable. (Done)
  • [x] An open question about go/types.EmbeddedFieldKind. (Resolved; no change required)
  • [x] Possibly landing CL 644255 in x/crypto so that blake2b implements the new hash.XOF interface. Since this is an x repo and x/crypto/blake2b is not vendored into std, this is less critical.
