Subject: [PATCH 0/4] kobject: properly warn on missing release function

This series contains:
* Patch 1 & 2: some cleanups for the logging in kobject.c
* Patch 3: Moves the validation of the release function from cleanup()
  to add() so the messages are not shown during shutdown where they are
  hard to see.
* Patch 4: Increases the logging level for the release function
  validation.

Please note that Patch 4 will trigger warnings on boot on at least all
machines with ACPI or block devices.
So this patch should probably not be applied yet.

The block dev part is being worked on here:
