When creating an inode, through btrfs_create_new_inode(), we release the path we allocated before once we don't need it anymore. But we keep it allocated until we return from that function, which is wasteful because after we release the path we do several things that can allocate yet another path: inheriting properties, setting the xattrs used by ACLs and secutiry modules, adding an orphan item (O_TMPFILE case) or adding a dir item (for the non-O_TMPFILE case). So instead of releasing the path once we don't need it anymore, free it instead. This way we avoid having two paths allocated until we return from btrfs_create_new_inode().

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 Restructured Text 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.
