Subject[PATCH v3 0/5] module autoloading fixes and cleanups
Date
This series fixes a bug where request_module() was reporting success to
kernel code when module autoloading had been completely disabled via
'echo > /proc/sys/kernel/modprobe'.

It also addresses the issues raised on the original thread
(https://lkml.kernel.org/lkml/20200310223731.126894-1-ebiggers@kernel.org/T/#u)
by documenting the modprobe sysctl, adding a self-test for the empty
path case, and downgrading a user-reachable WARN_ONCE().

Changed since v2:
- Adjusted the new documentation to avoid implicitly bringing up
module aliases, which are a more complex topic.
- Split the selftest patch into two patches, one to fix the test
numbering bug and one to add the new tests.

Changed since v1:
- Added patches to address the other issues raised on the thread.
