Merge branch 'tipc_net-next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux 



Paul Gortmaker says:

====================
This is the same eight commits as sent for review last week[1],
with just the incorporation of the pr_fmt change as suggested
by JoeP.  There was no additional change requests, so unless you
can see something else you'd like me to change, please pull.
 ...
Erik Hugne (5):
      tipc: use standard printk shortcut macros (pr_err etc.)
      tipc: remove TIPC packet debugging functions and macros
      tipc: simplify print buffer handling in tipc_printf
      tipc: phase out most of the struct print_buf usage
      tipc: remove print_buf and deprecated log buffer code

Paul Gortmaker (3):
      tipc: factor stats struct out of the larger link struct
      tipc: limit error messages relating to memory leak to one line
      tipc: simplify link_print by divorcing it from using tipc_printf
====================

	int "Size of log buffer"

	default "0"

	help

	  Size (in bytes) of TIPC's internal log buffer, which records the

	  occurrence of significant events.  Can range from 0 to 32768 bytes;

	  default is 0.



	  There is no need to enable the log buffer unless the node will be

	  managed remotely via TIPC.



config TIPC_DEBUG

	bool "Enable debugging support"

	default n

	help

	  Saying Y here enables TIPC debugging capabilities used by developers.

	  Most users do not need to bother; if unsure, just say N.



	  Enabling debugging support causes TIPC to display data about its

	  internal state when certain abnormal conditions occur. It also

	  makes it easy for developers to capture additional information of

	  interest using the dbg() or msg_dbg() macros.
