Oh, yes, CONFIG_POSIX_ACL. My bad.

You know what - scratch this patch. Sorry for the noise.

Some of the posix_acl.h functions are guarded by ifdef/ifndef
CONFIG_FS_POSIX_ACL, and some are not. This can break the build
if the code in question doesn't use ifdef CONFIG_FS_POSIX_ACL
(which happens with our code). But this patch is not enough,
apparently, we need to add ifdef CONFIG_FS_POSIX_ACL to our
code anyway, because of, for instance, posix_acl_alloc() which
is undefined for !FS_POSIX_ACL builds. Sorry for the noise.
