当前的xfs文件系统似乎已经默认/强制开启了acl，不用在mount时增加acl参数，fstab里加acl参数也被认为是无效的(会报错，说acl是不识别选项，mount会失败)。
kernel里xfs开启支持acl，那么mount上的xfs的acl就有效，测试getfacl和setfacl都有效。
环境：
gentoo，kernel-3.2.12-gentoo x86_64
zgrep -i "acl" /proc/config.gz
CONFIG_REISERFS_FS_POSIX_ACL=y
CONFIG_XFS_POSIX_ACL=y
# CONFIG_BTRFS_FS_POSIX_ACL is not set
CONFIG_FS_POSIX_ACL=y
CONFIG_GENERIC_ACL=y
CONFIG_TMPFS_POSIX_ACL=y
