From 9ec491447b90ad6a4056a9656b13f0b3a1e83043 Mon Sep 17 00:00:00 2001 From: Daniel Wagner Date: Thu, 11 Mar 2021 16:19:17 +0100 Subject: block: Suppress uevent for hidden device when removed 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.
