Compilation problems on 7.10

Hi Group,

Below is the code segment that does not compile on UBUNTU 7.10 after including AppArmor patches (variable "_KSL" is "kernel-sub-level" = 22):
---------------------
struct dentry *dentry;
struct iattr attr;
int error;
#if _KSL > 21 && defined(CONFIG_SUSE_KERNEL)
        error = notify_change(dentry,NULL,&attr);
#else
        error = notify_change(dentry,&attr);
#endif
---------------------
It compiles fine on Vanilla Kernel and OpenSuse 10.3
Is there a variable similar to CONFIG_UBUNTU_KERNEL that I can use to pass correct number of parameters to "notify_change" ?

Regards,
Alex.
