Enable CONFIG_TASK_IO_ACCOUNTING in Linux kernel config

[fstab]

What Happened?

OpenTelemetry process metrics use a file /proc/<pid>/io (via gopsutil) for reading IO stats (see Host Metrics Receiver). However, the file is not present on Minikube nodes because the kernel config CONFIG_TASK_IO_ACCOUNTING isn't enabled.

Same with Grafana Beyla's process metrics, they don't work on Minikube nodes either.

Could you enable it the CONFIG_TASK_IO_ACCOUNTING kernel config?

Maybe related: #22134

Attach the log file

open /proc/1852/io: no such file or directory

Operating System

Driver

Hi @fstab , that config was already enabled for ARM64 but not x86_64.

This will be fixed when #22758 lands.
