Date: Wed, 12 Oct 2022 08:15:17 +1300 From: Paulo Miguel Almeida <paulo.miguel.almeida.rodenas@...il.com> To: Christine Caulfield <ccaulfie@...hat.com>, David Teigland <teigland@...hat.com>, cluster-devel@...hat.com Cc: paulo.miguel.almeida.rodenas@...il.com, linux-kernel@...r.kernel.org, linux-hardening@...r.kernel.org Subject: [PATCH] [next] dlm: replace one-element array with fixed size array One-element arrays are deprecated. So, replace one-element array with fixed size array member in struct dlm_ls, and refactor the rest of the code, accordingly.
