Technical description

In the Linux kernel, the following vulnerability has been resolved:

ext4: fix access to uninitialised lock in fc replay path

The following kernel trace can be triggered with fstest generic/629 when

executed against a filesystem with fast-commit feature enabled:

INFO: trying to register non-static key.

The code is fine but needs lockdep annotation, or maybe

you didn't initialize this object before use?

turning off the locking correctness validator.
