The TO is subjected to specification of devices with lesser hardware capabilities that are included in the same OpenWrt target class (mvbeu > cortexa9), in this case to devices with 3 MiB kernel partition space, which OpenWrt is struggling to cope with as the kernel source code keeps on growing.
In the unlikely event that OpenWrt will be enabling those kconfig flags and in case TOS developers neither enabling the flags in their toolchain one would be left to build a kernel without those restraints.
Does iotop work for you in the latest TurrisOS 5?
This solution worked for me on TOS3 but not anymore on TOS5, I got this error when trying to run it:
