I would suggest describing explicitly in the commit message what you
want to do, which you said here e.g. "I do this because I want to add
LSM hooks". This also relevant information for the LKM discussion.

Lets see how the next version looks like now that you have some
feedback.

In the whole scope of the patch set, in order to make it more
readable, I'll give following suggestions on how it is organized:

1. Leave out anything that is not strictly necessary (cosmetic
fix, batch operation if possible). Better to focus one thing at
a time.
2. Try to organize it so that each function is fully defined in
the scope of one patch even if it would mean larger patches.
3. Do not add one call site helpers unless there is a good
reason to do so. A good reason would be something like needing
to extensive work in error rollback, which would make the
caller a mess.
