Description
Maintainer: @champtar
Environment: all, OpenWrt 19.07 and OpenWrt master
Description:
If you would like to know I/O rate of read/write for processes which helps you to know which processes are writing it to flash memory, it is necessary to enable these kernel configs:
Both kernel options are not set.
https://github.com/openwrt/openwrt/blob/openwrt-19.07/target/linux/generic/config-4.14#L4875
https://github.com/openwrt/openwrt/blob/openwrt-19.07/target/linux/generic/config-4.14#L4873
And this is same for OpenWrt master:
https://github.com/openwrt/openwrt/blob/master/target/linux/generic/config-5.4#L5474
https://github.com/openwrt/openwrt/blob/master/target/linux/generic/config-5.4#L5472
Otherwise, htop shows you no perm.

This prevents to fully use htop. Can you please enable it in OpenWrt main repository?

Research direction
Start by checking the referenced kernel configuration files, target/linux/generic/config-4.14 and config-5.4, in the relevant OpenWrt branches. Verify whether IO_ACCOUNTING and TASK_DELAY_ACCT are unset, then check the resulting htop behavior. Done means the required options are enabled for the supported configurations and htop no longer reports no perm.
