Subject: [PATCH] seq_file: use proc_create() in documentation
Date: Sat, 5 Dec 2009 03:42:04 +0300	[thread overview]
Message-ID: <20091205004204.GE16465@x200> (raw)

Using create_proc_entry() + ->proc_fops assignment is racy because
->proc_fops will be NULL for some time, use proc_create() to avoid race.
