Subject: [ISSUE] linux: missing bfq i/o scheduler
Date: Tue, 18 Jun 2019 19:22:25 +0200 [thread overview]

New issue by huglovefan on void-packages repository
https://github.com/void-linux/void-packages/issues/12530
Description: ### System
* xuname: `Void 5.1.11_1 x86_64-musl AuthenticAMD uptodate rFF`
* package: `linux4.14` and newer (only tested `5.1` but `bfq` was added in `4.12`)
### Expected behavior
`bfq` should be listed and selectable in `/sys/class/block/*/queue/scheduler`
### Actual behavior
it's not built into the kernel because the configuration option is unset
```
% cat /sys/class/block/sd[ab]/queue/scheduler
[mq-deadline] kyber none
[mq-deadline] kyber none
% zcat /proc/config.gz | grep BFQ
# CONFIG_IOSCHED_BFQ is not set
```
the default is `mq-deadline` but `bfq` is supposedly [better](https://algo.ing.unimo.it/people/paolo/disk_sched/results.php) for responsiveness under load
### Steps to reproduce the behavior
1. boot into `linux5.1`
2. look in `/sys/class/block/*/queue/scheduler`
