From a0016ff2867ad25aad9807fb46bd0d85429dd5e8 Mon Sep 17 00:00:00 2001 From: Fabian Frederick Date: Thu, 16 Apr 2015 12:48:15 -0700 Subject: fs/affs: use AFFS_MOUNT prefix for mount options Currently, affs still uses direct access on mount_options. This patch prepares to use affs_clear/set/test_opt() like other filesystems.
