Andreas Gruenbacher 764a5c6b1f xattr handlers: Simplify list operation
Change the list operation to only return whether or not an attribute
should be listed.  Copying the attribute names into the buffer is moved
to the callers.

Since the result only depends on the dentry and not on the attribute
name, we do not pass the attribute name to list operations.

Andreas Gruenbacher 98e9cb5711 vfs: Distinguish between full xattr names and proper prefixes
Add an additional "name" field to struct xattr_handler.  When the name
is set, the handler matches attributes with exactly that name.  When the
prefix is set instead, the handler matches attributes with the given
prefix and with a non-empty suffix.

This patch should avoid bugs like the one fixed in commit c361016a in
the future.

Andreas Gruenbacher 0ddaf72c1d squashfs: xattr simplifications
Now that the xattr handler is passed to the xattr handler operations, we
have access to the attribute name prefix, so simplify the squashfs xattr
handlers a bit.

Andreas Gruenbacher d9a82a0403 xattr handlers: Pass handler to operations instead of flags
The xattr_handler operations are currently all passed a file system
specific flags value which the operations can use to disambiguate between
different handlers; some file systems use that to distinguish the xattr
namespace, for example.  In some oprations, it would be useful to also have
access to the handler prefix.  To allow that, pass a pointer to the handler
to operations instead of the flags value alone.

Sparse does not like inline function declared without body,
because it is not part of the standard kernel practice.

The xattr_handler tables can be declared static.
