5.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Deepak Rawat drawat@vmware.com
commit 4b9ce3a651a37c60527101db4451a315a8b9588f upstream.
If it's not a system error and get_node implementation accommodate the buffer object then it should return 0 with memm::mm_node set to NULL.
v2: Test for id != -ENOMEM instead of id == -ENOSPC.
