Subject: [PATCH v3 0/3] Improve trace/ring_buffer.c
Date: Fri, 3 Mar 2023 16:17:03 +0100 [thread overview]
Message-ID: <20230303151706.57851-1-ubizjak@gmail.com> (raw)
This series improves ring_buffer.c by changing the type of some
static functions to void or bool and uses try_cmpxchg instead of
cmpxchg (*ptr, old, new) == old where appropriate.
v2: Convert only loops with cmpxchg.
v3: Rearrange variable declarations.
