kernel source refers to non-existent CONFIG variables

from the output of a scanning script i have, there are a number of
CONFIG variables that are tested in the linux kernel source but are not defined anywhere in a Kconfig file:

fs/nilfs2/inode.c:312:#ifdef CONFIG_NILFS_FS_POSIX_ACL fs/nilfs2/inode.c:437:#ifdef CONFIG_NILFS_FS_POSIX_ACL

fs/nilfs2/nilfs.h:61:#ifdef CONFIG_NILFS_POSIX_ACL fs/nilfs2/nilfs.h:200:#ifdef CONFIG_NILFS_POSIX_ACL fs/nilfs2/super.c:192:#ifdef CONFIG_NILFS_POSIX_ACL

fs/nilfs2/nilfs.h:51:#ifdef CONFIG_NILFS_XATTR
fs/nilfs2/super.c:165:#ifdef CONFIG_NILFS_XATTR

Hi!

These features are planned but not embarked on.
That is the reason why they are left there.

When we really implement them, of course, we will declare in the Kconfig file.

Thanks for the feedback.
