Subject: [PATCH] scsi: mptsas: Fixup device hotplug for VMWare ESXi
Git-commit: ee3e2d8392f695343d2fdfd43e881d14fb406d24
Patch-Mainline: v4.14-rc1
References: bsc#1129046
VMWare ESXi emulates an mptsas HBA, but exposes all drives as
direct-attached SAS drives. This it not how the driver originally
envisioned things; SAS drives were supposed to be connected via an
expander, and only SATA drives would be direct attached. As such, any
hotplug event for direct-attach SAS drives was silently ignored, and the
guest failed to detect new drives from within a VMWare ESXi environment.
