[ Upstream commit 313ef70a9f0f637a09d9ef45222f5bdcf30a354b ]
Inside print_data_reloc_error(), if extent_from_logical() failed we
return immediately.
However there are the following cases where extent_from_logical() can
return error but still holds a path:
- btrfs_search_slot() returned 0
- No backref item found in extent tree
- No flags_ret provided
This is not possible in this call site though.
So for the above two cases, we can return without releasing the path,
causing extent buffer leaks.
Fixes: b9a9a85059 ("btrfs: output affected files when relocation fails")

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.
