After calling btrfs_delete_one_dir_name() there's no need for the path anymore so we can free it immediately after. After that point we do some btree operations that take time and in those call chains we end up allocating paths for these operations, so we're unnecessarily holding on to the path we allocated early at __btrfs_unlink_inode(). So free the path as soon as we don't need it and add a comment. This also allows to simplify the error path, removing two exit labels and returning directly when an error happens.

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.
