The code checks newfe_bh for NULL after it has already been dereferenced to access b_data. This NULL check is unnecessary for two reasons: 1. If ocfs2_inode_lock() succeeds (returns >= 0), newfe_bh is guaranteed to be valid. 2. We've already dereferenced newfe_bh to access b_data, so it must be non-NULL at this point. Remove the redundant NULL check in the trace_ocfs2_rename_over_existing() call to improve code clarity.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
