Subject: [PATCH] sched: correct SD_flags returned by tl->sd_flags()
Date: Tue, 9 Jun 2020 23:09:36 +0800 [thread overview]
Message-ID: <20200609150936.GA13060@iZj6chx1xj0e0buvshuecpZ> (raw)
During sched domain init, we check whether non-topological SD_flags are
returned by tl->sd_flags(), if found, fire a waning and correct the
violation, but the code failed to correct the violation. Correct this.
Fixes: 143e1e28cb40 ("sched: Rework sched_domain topology definition")
