+Subject: [PATCH] mb/supermicro/x11-lga1151-series: Enable SATA hotplug
+
+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).
