Subject: module loader dead code removal and cleanups v2
Date: Thu, 28 Jan 2021 19:14:08 +0100 [thread overview]
Message-ID: <20210128181421.2279-1-hch@lst.de> (raw)
Hi all,
this series removes support for long term unused export types and
cleans up various loose ends in the module loader.
Changes since v1:
- move struct symsearch to module.c
- rework drm to not call find_module at all
- llow RCU-sched locking for find_module
- keep find_module as a public API instead of module_loaded
- update a few comments and commit logs
