From 59f740a6aeb2cde2f79fe0df38262d4c1ef35cd8 Mon Sep 17 00:00:00 2001 From: Zach Brown Date: Tue, 3 Aug 2010 13:52:47 -0700 Subject: RDS/IB: print string constants in more places This prints the constant identifier for work completion status and rdma cm event types, like we already do for IB event types. A core string array helper is added that each string type uses.
