Subject: [PATCH 0/2] rbree: inline rb_first() and rb_last()
Date: Fri, 14 Nov 2025 14:06:44 +0000 [thread overview]
Message-ID: <20251114140646.3817319-1-edumazet@google.com> (raw)
Inline these two small helpers, heavily used in TCP and FQ packet scheduler,
and in many other places.
This reduces kernel text size, and brings an 1.5 % improvement on network
TCP stress test.
Eric Dumazet (2):
rbtree: inline rb_first()
rbtree: inline rb_last()
