From 683ec9ba887d096a6cbd9a5778be9400efe6468c Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Tue, 6 Apr 2021 07:02:04 -0700 Subject: [PATCH] xfs: default attr fork size does not handle device inodes Device inodes have a non-default data fork size of 8 bytes as checked/enforced by xfs_repair. xfs_default_attroffset() doesn't handle this, so lets do a minor refactor so it does.
