Subject: [PATCH v2] sched/debug: Fix requested task uclamp values shown in procfs

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 <>
Signed-off-by: Pavankumar Kondeti <>

V2: Added "requested" prefix (suggested by Valentin)
