Date: Mon, 4 Apr 2016 16:26:37 -0400 From: Martin Brandenburg <martin@...ibond.com> To: hubcap@...ibond.com Cc: linux-kernel@...r.kernel.org, linux-fsdevel@...r.kernel.org, Martin Brandenburg <martin@...ibond.com> Subject: [PATCH 2/3] orangefs: strncpy -> strlcpy From: Martin Brandenburg <martin@...ibond.com> Almost everywhere we use strncpy we should use strlcpy. This affects path names (d_name mostly), symlink targets, and server names. Leave debugfs code as is for now, though it could use a review as well.
