[ Upstream commit 800d0b9b6a8b1b354637b4194cc167ad1ce2bdd3 ]
commit 8b0ba61df5a1 ("fs/xattr.c: fix simple_xattr_list to always
include security.* xattrs") failed to reset err after the call to
security_inode_listsecurity(), which returns the length of the
returned xattr name. This results in simple_xattr_list() incorrectly
returning this length even if a POSIX acl is also set on the 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.
