Merge branch 'tipc_fragmentation'
Erik Hugne says:
====================
tipc: message reassembly using fragment chain
We introduce a new reassembly algorithm that improves performance
and eliminates the risk of causing out-of-memory situations.
v3: -Use skb_try_coalesce, and revert to fraglist if this does not succeed.
-Make sure reassembly list head is uncloned.
v2: -Rebased on Ying's indentation fix.
-Node unlock call in msg_fragmenter case moved from patch #2 to #1.
('continue' with this lock held would cause spinlock recursion if only
patch #1 is used)
