Dear kernel developers! Something unintended must have happened in kernel version 4.20.0. On my PC I have an Iomega REV 35 drive. Up to kernel version 4.19.125 that device can be mounted with write access for the root user. (Unfortunately I could not find a way to have write access as a normal user.) The command I use for mounting: ----- sudo mount -t udf -o rw,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8 /dev/sr1 /media/rm_l1604/REV35 ----- The very same command gives the following message with kernel versions >= 4.20.0. ----- mount: /dev/sr1 is write-protected, mounting read-only ----- As a result there is no chance go get write access to the device. At least I could not find a way to get write access. Is there any workaround for this problem? Please let me know! Thank you and best regards, Reinhold Mannsberger
