Speaking of CERROR and logging, it it really useful
for each CERROR use to have 2 static structs?

In CERROR -> CDEBUG_LIMIT there is a:
	static struct cfs_debug_limit_state cdls;
	(12 or 16 bytes depending on 32/64 bit arch)

and in CDEBUG_LIMIT -> _CDEBUG
	static struct libcfs_debug_msg_data msgdata;
	(24 or 36 bytes depending on 32/64 bit arch)

That seems a largish bit of data and code to initialize
these structs for over a thousand call sites.

Wouldn't a single static suffice?
