[PATCH v3 0/9] um: Minor fixes and cleanups
Posted by Tiwei Bie 1 year, 9 months ago
A series of minor fixes and cleanups for UML.

Most changes in this series are very straightforward. Please consider
picking this series for v6.9.

There are still some remaining -Wmissing-prototypes warnings. I plan to
send a followup RFC series first to fix those warnings.

Feedbacks on this series would be appreciated. Thanks!

Changes since v2:
https://lore.kernel.org/lkml/20240205114708.25235-1-tiwei.btw@antgroup.com/
- Add "um: Move declarations to proper headers";
- Add "um: Fix -Wmissing-prototypes warnings for text_poke*";
- Add "um: Fix -Wmissing-prototypes warnings for __warp_* and foo";
- Make do_set_thread_area() static;
- Add the missing header for calibrate_delay_is_known;

Tiwei Bie (9):
  um: Make local functions and variables static
  um: Fix the declaration of vfree
  um: Remove unused functions
  um: Fix the return type of __switch_to
  um: Add missing headers
  um: Stop tracking host PID in cpu_tasks
  um: Move declarations to proper headers
  um: Fix -Wmissing-prototypes warnings for text_poke*
  um: Fix -Wmissing-prototypes warnings for __warp_* and foo

LGTM, thanks.

For the series, including 8 and 9 that were discussed before
(but Richard, feel free not to add that individually):

Reviewed-by: Johannes Berg <johannes@sipsolutions.net>

I also did build-testing for this, on 64-bit only though right now.

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@emeril.freedesktop.org:

https://lore.kernel.org/all/87bk7rzj70.fsf@intel.com/

Thanks,
Tiwei

yeah, it's a clear improvement.

For patches 1-5 and 7, feel free to add my Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com>
I commented on patch 8 as I'm not sure it's the right approach and same
thing applies to patch 9.  Patch 6 I'm just not sure as it's the first
time I see that file, so I will leave it to others.

thanks
