Subject: rxrpc: Fix handling of enums-to-string translation in tracing
X-Git-Tag: v4.14-rc1~1433^2~93^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b54a134a7de461f804cf0e28331d0a43ee82fb13;p=platform%2Fkernel%2Flinux-rpi.git

rxrpc: Fix handling of enums-to-string translation in tracing

Fix the way enum values are translated into strings in AF_RXRPC
tracepoints.  The problem with just doing a lookup in a normal flat array
of strings or chars is that external tracing infrastructure can't find it.
Rather, TRACE_DEFINE_ENUM must be used.

Also sort the enums and string tables to make it easier to keep them in
order so that a future patch to __print_symbolic() can be optimised to try
a direct lookup into the table first before iterating over it.

A couple of _proto() macro calls are removed because they refered to tables
that got moved to the tracing infrastructure.  The relevant data can be
found by way of tracing.
