31 * The const keyword was added to the 'struct xattr_handler' in the
32 * generic Linux super_block structure. To handle this we define an
33 * appropriate xattr_handler_t typedef which can be used. This was
34 * the preferred solution because it keeps the code clean and readable.

37 typedef const struct xattr_handler xattr_handler_t;
39 typedef struct xattr_handler xattr_handler_t;
44 * The xattr_hander->get() callback was changed to take a dentry
45 * instead of an inode, and a handler_flags argument was added.
