[LU-12257] Modify existing CDEBUG/CERROR messages in LNet to provide more useful information

Tue, 28 May 2019 13:59:40 +0000

There are a large number of CDEBUG and CERROR messages that could provide more useful information when debugging problems. In particular, any message that references an lnet_msg would be vastly more helpful if it included the address of the lnet_msg pointer.

There are similar opportunities with other important LNet data structures such as the lnet_peer, lnet_peer_ni, etc.

As a first pass we can make some incremental improvements to existing messages by just including pointer addresses, but we may also want to investigate whether it would be useful to include a standardized set of information and create a macro, similar to the DEBUG_REQ or LDLM_DEBUG macros, and convert appropriate CDEBUG messages over to the macro.
