Subject: [PATCH] kdb: Remove redundant module related references

Hi Luis, Christoph, Daniel,

Is this patch ok or would you rather another iteration of the series?
Either way is fine for me. Thanks.


No functional change.

There is no need to include linux/module.h.
This patch addresses the above. Furthermore, we remove the list of known
loaded modules i.e. stored in 'kdb_modules', since it is now redundant.

Fixes: 260681b3763f ("module: Move kdb module related code out of main kdb code")
