Currently ll_initxattrs() initializes the security xattrs in a very non-standard using get_xattr_types() to get the struct handler that lustre created to then call indirectly the function to set the xattr. The available __vfs_setxattr() function does the same thing and also handles the case of when size is zero the xattr should be set to empty EA.
