From: Daniel Wagner <dwagner@suse.de> stable inclusion from linux-4.19.184 commit 4c083481b30a17568273deed595736e091d17a65 -------------------------------- [ Upstream commit 9ec491447b90ad6a4056a9656b13f0b3a1e83043 ] register_disk() suppress uevents for devices with the GENHD_FL_HIDDEN but enables uevents at the end again in order to announce disk after possible partitions are created. When the device is removed the uevents are still on and user land sees 'remove' messages for devices which were never 'add'ed to the system. KERNEL[95481.571887] remove /devices/virtual/nvme-fabrics/ctl/nvme5/nvme0c5n1 (block) Let's suppress the uevents for GENHD_FL_HIDDEN by not enabling the uevents at all.
