The special ones show up as /dev/mmcblk1boot0 and /dev/mmcblk1rpmb respectively. The kernel drivers for the eMMC device automatically detect this situation and write-protect these special devices unless you specifically enable writes via a switch in /proc. Calling parted -l however attempts to open these devices read-write.=20 Which fails and generates a dmesg entry that, prior to the 4.14 kernel, was difficult to distinguish from the messages generated by a failing eMMC device. To keep the logs clean and for safety in the case of someone enabling writes to these devices for various reasons, parted should probably do what it can to leave them alone unless specifically instructed to do otherwise. Poking these devices in the wrong way can potentially brick the motherboard, so an extra layer of defense around them would seem prudent. For my own purposes I will simply remove these device nodes from my system as I have no need of them, so I do not personally consider this to be a critical issue. Those who actually make use of these special devices may disagree though. https://dev-nell.com/rpmb-emmc-errors-under-linux.html documents a different issue, but has some code references that may be useful for determining how best to construct a filter for these special devices.

Or have distros just been applying patches themselves and continuing to call it 3.2? There are some unstable packages I could try if that's the case just to see if they've pulled that commit in.

I pulled the repo you linked and tested it. It also still generates the error messages in the kernel log. I had assumed that the problem was opening the device read/write due to the wording of the dmesg error from kernel 4.14. This may have been a premature assumption on my part. (Or maybe not, see below.) Running parted -l or partprobe with the version from the above repo results in: Warning: Error fsyncing/closing /dev/mmcblk1rpmb: Input/output error Interestingly the 3.2 release version prints the user error twice and the dmesg error three times while the version from the above repo only prints the user error once and the dmesg error twice. So it's also possible that this commit had some effect but the program goes on to open the device read/write a couple of times anyway. If you need access to a device with an rpmb for testing anything, let me know. I can probably arrange it. LMP
