Subject: Re: [RFC PATCH v2 00/13] module: core code clean up

Hi Aaron,

  Was the code compile tested?

  Unfortunately, I could not apply the series cleanly on top of the
latest 5.17-rc1.
  I did rebase the patches and fixed minor compile time failures as
well a few small checkpatch errors.
  I have pushed the series to
https://github.com/allenpais/Linux/commits/refactor_module_v3
  [The series now is based on
   84bfcc0b6994 2022-01-11 Merge tag 'integrity-v5.17' of
git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity]

  So far I could only manage to compile test the patches. Will test it
on BM(x86/arm) in a day or two.

Thanks,
- Allen
