Compiling kernel/ causes warnings:
... ‘root’ may be used uninitialized in this function ... ‘root’ was declared here
This isn't an issue since there is already logic to not use root if we goto out_unlock without setting root.
Explicitly initialize root to NULL to suppress this so that we can focus on catching warnings that can potentially cause bigger issues.
