Thanks. > "BFQ merged a couple of years ago." Okay, got it. My question was driven by confusion of what exactly was package https://aur.archlinux.org/packages/linux-rt-bfq/ https://aur.archlinux.org/packages/linux-rt-bfq/ . Reading now the wiki in GitHub ( https://github.com/sirlucjan/bfq-mq-lucjan/wiki https://github.com/sirlucjan/bfq-mq-lucjan/wiki ), it's clear: > Development version of BFQ > The development version of BFQ [...] differs from the production version in that: > - it contains commits not available for that kernel version; > - it contains a lot of consistency checks to detect possible malfunctions. So, linux-rt-bfq is linux-rt, sprinkled with extra fixes to bfq unmerged yet to mainline.
