Subject: [PATCH v4 1/4] sched/topology: Remove duplicate descriptions from TOPOLOGY_SD_FLAGS
Date: Wed, 7 Feb 2024 11:47:01 +0800 [thread overview]
Message-ID: <20240207034704.935774-1-alexs@kernel.org> (raw)
From: Alex Shi <alexs@kernel.org>
These flags are already documented in include/linux/sched/sd_flags.h.
Also add missing SD_CLUSTER and keep the comment on SD_ASYM_PACKING
as it is a special case.
