This test is motivated by an issue found by a btrfs user, addressed and described by the following GNU/Linux kernel patch: https://patchwork.kernel.org/patch/3046931/ The steps to reproduce the issue on btrfs are the following: $ mkfs.btrfs -f /dev/loop0 $ mount /dev/loop0 /mnt $ mkdir /mnt/acl $ setfacl -d --set u::rwx,g::rwx,o::- /mnt/acl $ getfacl /mnt/acl user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:other::--- $ mkdir /mnt/acl/dir1 $ getfacl /mnt/acl/dir1 user::rwx group::rwx other::--- After unmounting and mounting again the filesystem, getfacl returned the expected default ACL for the subdirectory: $ umount /mnt/acl $ mount /dev/loop0 /mnt $ getfacl /mnt/acl/dir1 user::rwx group::rwx other::--- default:user::rwx default:group::rwx default:other::--- This means that the underlying ACL xattr was persisted correctly but the in memory representation of the inode had (incorrectly) a NULL ACL.
