From ee102584efd53547bf9a0810e80b56f99f4a9105 Mon Sep 17 00:00:00 2001 From: Zhengyuan Liu Date: Thu, 20 Jun 2019 18:12:17 +0100 Subject: fs/afs: use struct_size() in kzalloc() As Gustavo said in other patches doing the same replace, we can now use the new struct_size() helper to avoid leaving these open-coded and prone to type mistake.
