From ab3629ed86ec43e7d95cf087d0b5a9d403fcd822 Mon Sep 17 00:00:00 2001 From: Chengguang Xu <cgxu519@gmx.com> Date: Wed, 27 Jun 2018 12:16:34 +0800 Subject: btrfs: return error instead of crash when detecting unexpected type in btrfs_get_acl The caller of btrfs_get_acl() checks error condition so there is no impact from this change. In practice there is no chance to get into default case of switch statement because VFS has already checked the type.
