The dirattr btree checking code uses the altpath substructure of the dirattr state structure to check the sibling pointers of dir/attr tree blocks. At the end of sibling checks, xfs_da3_path_shift could have changed multiple levels of buffer pointers in the altpath structure. Although we release the leaf level buffer, this isn't enough -- we also need to release the node buffers that are unique to the altpath. Not releasing all of the altpath buffers leaves them locked to the transaction. This is suboptimal because we should release resources when we don't need them anymore. Fix the function to loop all levels of the altpath, and fix the return logic so that we always run the loop. Signed-off-by: Darrick J.

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.
