All codepaths that don't want to implement POSIX ACLs should simply not implement the associated inode operations instead of relying on IOP_XATTR. That's the case for all filesystems today. For vfs_listxattr() all filesystems that explicitly turn of xattrs for a given inode all set inode->i_op to a dedicated set of inode operations that doesn't implement ->listxattr(). We can remove the dependency of vfs_listxattr() on IOP_XATTR. Removing this dependency will allow us to decouple POSIX ACLs from IOP_XATTR and they can still be listed even if no other xattr handlers are implemented. Otherwise we would have to implement elaborate schemes to raise IOP_XATTR even if sb->s_xattr is set to NULL. Signed-off-by: Christian Brauner (Microsoft) <brauner@kernel.org> |

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.
