default_acl and acl of newly created inode will be initiated as ACL_NOT_CACHED in vfs function inode_init_always() and later will be updated by calling xxx_init_acl() in specific filesystems. Howerver, when default_acl and acl are NULL then they keep the value of ACL_NOT_CACHED, this patch tries to cache NULL for acl/default_acl in this case.
