[PATCH] sched_ext: repair kernel-doc comments

From: Randy Dunlap

Date: Thu Jul 23 2026 - 13:50:35 EST


Add missing function parameter descriptions and use the correct
function name in kernel-doc comments to avoid kernel-doc warnings:

Warning: kernel/sched/ext/ext.c:2692 function parameter 'sch' not described in 'finish_dispatch'
Warning: kernel/sched/ext/ext.c:5309 function parameter 'stalled_mask' not described in 'scx_rcu_cpu_stall'
Warning: kernel/sched/ext/ext.c:5405 function parameter 'cpu' not described in 'scx_hardlockup'
Warning: kernel/sched/ext/ext.c:8470 expecting prototype for scx_bpf_dsq_insert(). Prototype was for scx_bpf_dsq_insert___v2() instead
Warning: kernel/sched/ext/ext.c:8784 expecting prototype for scx_bpf_dsq_move_to_local(). Prototype was for scx_bpf_dsq_move_to_local___v2() instead
Warning: kernel/sched/ext/ext.c:9498 expecting prototype for scx_bpf_reenqueue_local(). Prototype was for scx_bpf_reenqueue_local___v2() instead
