This patch completes commit 9548906b2bb7 ('xattr: Constify ->name member of "struct xattr"'). It fixes the documentation of the inode_init_security hook, by removing the xattr name from the objects that are expected to be allocated by LSMs (only the value is allocated). Also, it removes the kfree() of name and setting it to NULL in the reiserfs code.
