This function has the following pattern
while (1) {
ret = whatever();
if (ret)
goto out;
}
ret = 0
out:
return ret;
However several places in this while loop we simply break; when there's
a problem, thus clearing the return value, and in one case we do a
return -EIO, and leak the memory for the path.
Fix this by re-arranging the loop to deal with ret == 1 coming from
btrfs_search_slot, and then simply delete the
ret = 0;
out:
bit so everybody can break if there is an error, which will allow for
proper error handling to occur.

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.
