I've asked in the past to have a proper container for the ACLs in common code, but a union of a refcount and a rcu head doesn't really fit that category. But this points out that the f2fs folks really need a couple of slaps on their hands. Not if generic funtionality doesn't fit your needs you are not going to blindly copy and paste it, please talk to find a solution instead of duplicating it. Folks, please come up with a suggestion to get rid of f2fs_acl_clone, f2fs_acl_create_masq and f2fs_acl_create ASAP. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
