Subject: [PATCH 3/8] docs: kernel-doc: Move STATE_NORMAL processing into its own function
Date: Wed,  7 Feb 2018 10:26:19 -0700	[thread overview]
Message-ID: <20180207172624.24555-4-corbet@lwn.net> (raw)
In-Reply-To: <20180207172624.24555-1-corbet@lwn.net>

Begin the process of splitting up the nearly 500-line process_file()
function by moving STATE_NORMAL processing to a separate function.
