From 212209cff89fe497bc47abcd017aa95e4e8a5196 Mon Sep 17 00:00:00 2001 From: Jonathan Corbet Date: Fri, 26 Mar 2021 13:16:35 -0600 Subject: docs: kernel-doc: properly recognize parameter lines with colons The previous attempt to properly handle literal blocks broke parsing of parameter lines containing colons; fix it by tweaking the regex to specifically exclude the "::" pattern while accepting lines containing colons in general. Add a little documentation to the regex while in the neighborhood.
