Subject: [PATCH] image-fit: ignore rsa by image selection
Date: Thu, 11 Mar 2021 17:07:21 +0000 [thread overview]
Message-ID: <20210311170334.22607-1-denis.osterland@diehl.com> (raw)
From: Denis Osterland-Heim <Denis.Osterland@diehl.com>
For hash algorithm selection, only the first argument of the tuple is
needed. The ',' is included to avoid false-positive matches.
