** Description changed: [SRU Justification] [Impact] Memory card removal event can not be reflected via uevent on some card readers Ex. Realtek card readers 0bda:0328 and 0bda:0158. Thus the file browser still see the ghost disk even it's already removed. [Fix] - Make sure the partition scan will never be skipped for each vfs_open - until the partition scan is really done. - + Found the commit 6540fbf6b643 in 5.9.0-rc3 introduce this regression. + Fix it by making sure the partition scan will never be skipped for each + vfs_open until the partition scan is really done [Test] Verified on the Realtek card reader 0bda:0328 on Dell Precision 7820 and the external Realtek usb interface card reader 0bda:0158. - [Where problem could occur] These kind of card readers doesn't send remove event of scsi_disk and scsi_device like others so they only depend on the block subsystem to detect the media change and relect the removal event by partition scan. - If the remove event is not correcly reflected, the device node of the - media will remain there until next card insertion. - + The behavior related to media removal is changed after 5.9.0-rc3. + The remove event is not able to be correcly reflected since then, the + device node of the media will remain there until next card insertion. ========== Original Bug Description ========== Ubuntu version: 20.10 Kernel: 5.10.0-1013-oem Card reader: Realtek Card Reader (0bda:0328 and 0bda:0158) Summary ======= After upgrading to kernel 5.9.0-rc3 or later, the device node for the partitions on the memory cards will not disappear after removing the memory cards. This is confusing to the user level applications like File Browser since the partition label will remain there for a long time. Steps to reproduce ================== 1. Upgrade to kernel later than 5.9.0-rc3 2. Plug the external card reader and insert the formatted memory card 3. Verify if the memory card mounted and visible on File Browser 4. Remove the memory card from the card reader 5. Verify if the mounted memory card removed from the File Browser Expected results ================ The mounted memory card identifier should be disappear after remove the memory card Actual results ============== The partition label of the memory card exists for a long time. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu50 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: dev 1443 F.... pulseaudio /dev/snd/controlC0: dev 1443 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.10 InstallationDate: Installed on 2021-03-22 (0 days ago) InstallationMedia: Ubuntu 20.10 "Groovy Gorilla" - Release amd64 (20201022) MachineType: ASUSTeK COMPUTER INC.
