[PATCH v3 0/9] um: Minor fixes and cleanups

[Tiwei Bie]

Hi,

Gentle ping.. Please take a look at this series if possible. The changes
in this series are very straightforward, so it shouldn't require much effort
to review. But they cover a wide area, making them prone to conflicts
with other patches :/, e.g.

https://lore.kernel.org/linux-um/20240326073750.726636-1-surenb@google.com/T/#u

Sorry to be impatient, but pinging this. This series was originally posted
two months ago, and hasn't received a review yet. Just want to make sure that
this series is not lost..

PS. I have tested this series on both of 64bit and 32bit platforms manually.
There is also a CI test report from patchwork at emeril.freedesktop.org:

Thanks,
Tiwei
