The changes need to be address are:

LNet: kernel_getpeername() and kernel_getsockname() dropped last argument.

The struct address_mapping changed from radix to xarry. All llite changes.

Initialize "struct dentry_operations" .d_init using ll_d_init(). For proper parallel lookup support.

Remove LASSERT(atomic_read(&lli->lli_posix_acl->a_refcount) == 1);

That will do it.
