Subject: [PATCH 0/5] ALSA: seq: Optimization with RCU
Date: Mon, 10 Aug 2026 15:37:01 +0200 [thread overview]
Message-ID: <20260810133711.42483-1-tiwai@suse.de> (raw)
Hi,
here are a set of (rather small) patches for optimizing lockings in
ALSA sequencer core by replacing with RCU. Most of changes are
straight-forward conversions from read-lock to RCU, or a simple
pointer assignment.
