Subject: Clean-up: remove unused _trace_abi field from the CTF2 trace class visitor
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=4f2da8b8c0f8fad2ae35dbdb9f29769da52a3dc1;p=lttng-tools.git

Clean-up: remove unused _trace_abi field from the CTF2 trace class visitor

This unused field results in a build failure when using clang++ 14.0.6
with Werror.

  ./ctf2-trace-class-visitor.hpp:39:37: error: private field '_trace_abi' is not used [-Werror,-Wunused-private-field]
          const lttng::sessiond::trace::abi& _trace_abi;
