All messages should go directly to the kernel log. The TIPC
specific error, warning, info and debug trace macro's are
removed and all references replaced with pr_err, pr_warn,
pr_info and pr_debug.Commonly used sub-strings are explicitly declared as a const
char to reduce .text size.Note that this means the debug messages (changed to pr_debug),
are now enabled through dynamic debugging, instead of a TIPC
specific Kconfig option (TIPC_DEBUG). The latter will be
phased out completelySigned-off-by: Erik Hugne

Some of the comment blocks are floating in limbo between two
functions, or between blocks of code. Delete the extra line
feeds between any comment and its associated following block
of code, to be consistent with the majority of the rest of
the kernel. Also delete trailing newlines at EOF and fix
a couple trivial typos in existing comments.This is a 100% cosmetic change with no runtime impact. We get
rid of over 500 lines of non-code, and being blank line deletes,
they won't even show up as noise in git blame.Signed-off-by: Paul Gortmaker

Do some cleanups of TIPC based on make namespacecheck
1. Don't export unused symbols
2. Eliminate dead code
3. Make functions and variables local
4. Rename buf_acquire to tipc_buf_acquire since it is used in several filesCompile tested only.

So in the forward porting of various tipc packages, I was constantly
getting this lockdep warning everytime I used tipc-config to set a network
address for the protocol:[ INFO: possible circular locking dependency detected ]
2.6.33 #1
tipc-config/1326 is trying to acquire lock:
(ref_table_lock){+.-...}, at: [] tipc_ref_discard+0x53/0xd4 [tipc]but task is already holding lock:
(&(&entry->lock)->rlock#2){+.-...}, at: [] tipc_ref_lock+0x43/0x63 [tipc]which lock already depends on the new lock.
the existing dependency chain (in reverse order) is:

[] system_call_fastpath+0x16/0x1bFinally decided I should fix this. Its a straightforward inversion,
tipc_ref_acquire takes two locks in this order:
ref_table_lock
entry->lockwhile tipc_deleteport takes them in this order:
entry->lock (via tipc_port_lock())
ref_table_lock (via tipc_ref_discard())when the same entry is referenced, we get the above warning. The fix is equally
straightforward. Theres no real relation between the entry->lock and the
ref_table_lock (they just are needed at the same time), so move the entry->lock
aquisition in tipc_ref_acquire down, after we unlock ref_table_lock (this is
safe since the ref_table_lock guards changes to the reference table, and we've
already claimed a slot there. I've tested the below fix and confirmed that it
clears up the lockdep issueSigned-off-by: Neil Horman

This patch corrects many places where TIPC routines indicated
successful completion by returning TIPC_OK instead of 0.
(The TIPC_OK symbol has the value 0, but it should only be used
in contexts that deal with the error code field of a TIPC
message header.)Signed-off-by: Allan Stephens

This patch eliminates the (very remote) chance of a crash resulting
from a partially initialized socket or native port unexpectedly
receiving a message. Now, during the creation of a socket or native
port, the underlying generic port's lock is not released until all
initialization required to handle incoming messages has been done.Signed-off-by: Allan Stephens

This patch is a largely cosmetic cleanup of the TIPC reference
table code.
- The object reference field in each table entry is now single
32-bit integer instead of a union of two 32-bit integers.
- Variable naming has been made more consistent.
- Error message output has been made more consistent.
- Useless #includes have been eliminated.Signed-off-by: Allan Stephens

locking init cleanups:
- convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
- convert rwlocks in a similar mannerthis patch was generated automatically.
Motivation:
- cleanliness
- lockdep needs control of lock initialization, which the open-coded
variants do not give
- it's also useful for -rt and for lock debugging in generalSigned-off-by: Ingo Molnar

Tried to run the new tipc stack through sparse.
Following patch fixes all cases where 0 was used

Use NULL to document this is a pointer and to silence sparse.This brough sparse warning count down with 127 to 24 warnings.
