From 0b873de2c02f9cc655bef6bee0eb9e404126ed6c Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Wed, 26 Nov 2025 01:01:27 -0500 Subject: [PATCH] nfs/localio: remove 61 byte hole from needless ____cacheline_aligned struct nfs_local_kiocb used ____cacheline_aligned on its iters[] array and as the structure evolved it caused a 61 byte hole to form. Fix this by removing ____cacheline_aligned and reordering iters[] before iter_is_dio_aligned[].
