[Download RAW message or body]
DEFINE_DEBUGFS_ATTRIBUTE and debugfs_create_file_unsafe() were
introduced in mainline commit c6468808149 ("debugfs: add support for
self-protecting attribute file fops"), but on older kernel versions
where we do not have this extra security in debugfs we can use the older
functions instead.
