Subject: [PATCH v2] sched/debug: Fix requested task uclamp values shown in procfs
Date: Mon, 11 May 2020 07:23:30 +0530 [thread overview]
Message-ID: <1589162011-4998-1-git-send-email-pkondeti@codeaurora.org> (raw)
The intention of commit 96e74ebf8d59 ("sched/debug: Add task uclamp
values to SCHED_DEBUG procfs") was to print requested and effective
task uclamp values. The requested values printed are read from p->uclamp,
which holds the last effective values. Fix this by printing the values
from p->uclamp_req.
Fixes: 96e74ebf8d59 ("sched/debug: Add task uclamp values to SCHED_DEBUG procfs")
Tested-and-reviewed-by: Valentin Schneider <valentin.schneider@arm.com>
