Subject: [PATCH 0/2] tracing: Clean up of set_tracer_flag()
Date: Wed, 05 Nov 2025 19:33:24 -0500 [thread overview]
Message-ID: <20251106003324.964761749@kernel.org> (raw)
The set_tracer_flag() function takes a mask that has a single bit set.
It then goes through a bunch of "if ()" statements looking at what the
mask is to perform the necessary operations. It is simpler to switch that
over to a "switch ()" statement.
Steven Rostedt (2):
tracing: Exit out immediately after update_marker_trace()
tracing: Use switch statement instead of ifs in set_tracer_flag()
