Tejun Heo 4fda9f0e7c sched_ext: Guard scx_dsq_move() against NULL kit->dsq after failed iter_new ... bpf_iter_scx_dsq_new() clears kit->dsq on failure and bpf_iter_scx_dsq_{next,destroy}() guard against that. scx_dsq_move() doesn't - it dereferences kit->dsq immediately, so a BPF program that calls scx_bpf_dsq_move[_vtime]() after a failed iter_new oopses the kernel. Return false if kit->dsq is NULL.
