Thanks for the backport! It looks like argument clinic changed enough that it needs to be re-run on the changed file. Should be able to do python Tools\clinic\clinic.py -f Modules\_winapi.c and commit the change to get that last check to pass.

Why did you add an extra period in the commit message? Please remove it. I recall that cherry_picker had some sort of bug that could cause issues like this.

@zooba Can you please make sure that the extra period is not there when merging?

[lukegarland]

Removed the extra period in the commit message, and updated the argument clinic using python Tools\clinic\clinic.py -f Modules\_winapi.c

[ZackerySpytz]

No, you didn't remove it. It looks like you removed the period in 3.10 instead, which is wrong (please add it back).

In the sentence that begins with "In multiprocessing.shared_memory.SharedMemory", you added an extra period at the end. Please remove it.

Ah, thanks for the clarification. Was looking at the wrong commit. Its fixed now, and all checks pass.
