See the commit message in the patch: Before this patch, hotplugging only worked to replace drives (if you tried to plug a drive into a SATA port that no drive was plugged in to at boot, it wouldn't be detected) and you'd have to manually rescan the bus (echo "- - -" > /sys/class/scsi_host/host*/scan) to make plugs/unplugs get detected by the operating system. Now, hotplugging works for all ports (tested and working on Supermicro X11SSH-LN4F) and there's no need to manually rescan (it sometimes takes a few seconds for unplugs to be detected, but plugs are detected instantly).

Libreboot

Libera IRC
Libreboot provides libre boot firmware on supported motherboards. It replaces proprietary vendor BIOS/UEFI implementations, by
- Using coreboot to initialize the hardware (e.g. memory controller, CPU, etc.) while minimizing unwanted functionality (e.g. backdoors such as the Intel Management Engine)
- ... which runs a payload such as SeaBIOS, GRUB, or U-Boot
- ... which loads your operating system's boot loader (BSD and Linux-based systems are supported).
Why use Libreboot, and what is coreboot?
A lot of users who use libre operating systems still use proprietary boot firmware, which often contain backdoors and bugs, hampering user freedom and right to repair.
coreboot provides libre boot firmware by initializing the hardware then running a payload. However, coreboot is notoriously difficult to configure and install for most non-technical users, requiring detailed technical knowledge of hardware.
Libreboot solves this by being a coreboot distribution (in the same way that Alpine Linux is a Linux distribution). It provides a fully automated build system that downloads and compiles pre-configured ROM images for supported motherboards, so end-users could easily fetch images to flash onto their devices.
Libreboot also produces documentation aimed at non-technical users and excellent user support via IRC.
