Subject: [PATCH 07/14] header: debugfs.h: add DEFINE_DEBUGFS_ATTRIBUTE
Date: Sun,  4 Mar 2018 23:57:10 +0100	[thread overview]
Message-ID: <20180304225717.20890-8-hauke@hauke-m.de> (raw)
In-Reply-To: <20180304225717.20890-1-hauke@hauke-m.de>

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.
