I just reviewed 0007. It removes the second parameter "bool =
skip_recently_used=E2=80=9D  from SyncOneBuffer. The function is static =
and is only called in one place with skip_recently_used=3Dtrue, thus =
removing the parameter seems reasonable, and without considering pinned =
buffer, the function is simplified a little bit.

I only got a tiny comment:
```
+		 * We can make these check without taking the buffer =
content lock so
```=20

As you changed =E2=80=9Cthis=E2=80=9D to =E2=80=9Cthese=E2=80=9D, =
=E2=80=9Ccheck=E2=80=9D should be changed to =E2=80=9Cchecks=E2=80=9D =
accordingly.
