Re: [PATCH v2 0/1] MR8802: win32u: Avoid calling server in NtUserGetKeyState() when input keystate is in sync.

[Paul Gofman (＠gofman)]

v2:
 - don't introduce 'input_state' variable (assume shared memory read never fails);
 - rename `desktop_keystate_serial` to `keystate_serial`;
 - initialize input keystate serial to 1.
