Subject: [PATCH net-next 0/8] tipc: convert name table read-write lock to RCU

Now TIPC name table is statically allocated and is protected with a
Read-Write lock. To enhance the performance of TIPC name table lookup,
we are going to involve RCU lock to protect the name table. As a
consequence, it becomes lockless to concurrently look up name table on
read side. However, before the conversion can be successfully made,
the following two things must be first done:

- change allocation way of name table from static to dynamic
- fix several incorrect locking policy issues

Ying Xue (8):
  tipc: remove size variable from publ_list struct
  tipc: make name table allocated dynamically
  tipc: ensure all name sequences are released when name table is
    stopped
  tipc: ensure all name sequences are properly protected with its lock
  tipc: any name table member must be protected under name table lock
  tipc: simplify relationship between name table lock and node lock
  tipc: remove unnecessary INIT_LIST_HEAD
  tipc: convert name table read-write lock to RCU
