Subject: [PATCH 1/2] Documentation: sched_ext: fix events sysfs path and show_state example
Date: Tue, 11 Aug 2026 15:38:00 +0800 [thread overview]
Message-ID: <20260811073801.342165-2-cui.tao@linux.dev> (raw)
In-Reply-To: <20260811073801.342165-1-cui.tao@linux.dev>
From: Tao Cui <cuitao@kylinos.cn>
The events file is under the scheduler's sysfs kobject
(/sys/kernel/sched_ext/root/events for the root scheduler), not the
nonexistent "<scheduler-name>/events" path. Also add the missing "aborting"
line to the scx_show_state.py example.
