Subject: [PATCH v7 05/16] tracing: probeevent: Unify fetch type tables
Date: Wed, 25 Apr 2018 21:18:32 +0900
Message-ID: <152465871274.26224.13999436317830479698.stgit@devbox> (raw)
In-Reply-To: <152465856498.26224.16969986455942749517.stgit@devbox>

Unify {k,u}probe_fetch_type_table to probe_fetch_type_table
because the main difference of those type tables (fetcharg
methods) are gone. Now we can consolidate it.
