Subject: [for-next][PATCH 02/13] tracing: Remove unused variable in tracing_trace_options_show()
Date: Thu, 27 Nov 2025 20:23:33 -0500 [thread overview]
Message-ID: <20251128012411.146707328@kernel.org> (raw)
In-Reply-To: 20251128012331.307010654@kernel.org
From: Steven Rostedt <rostedt@goodmis.org>
The flags and opts used in tracing_trace_options_show() now come directly
from the trace array "current_trace_flags" and not the current_trace. The
variable "trace" was still being assigned to tr->current_trace but never
used. This caused a warning in clang.
