This function can return a negative error value if btrfs_search_slot errors for whatever reason or if btrfs_alloc_path runs out of memory. This is currently problemattic because backref_in_log is treated by its callers as if it returns boolean. Fix this by adding proper error handling in callers. That also enables the function to return the direct error code from btrfs_search_slot.

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.
