I mean sure we can do this. But we should try without a Kconfig option for this. But mount(8) and util-linux have been switched to the new mount api in v2.39 and libmount already has the code to read and print the error messages: https://github.com/util-linux/util-linux/blob/7ca98ca6aab919f271a15e40276cbb411e62f0e4/libmount/src/hook_mount.c#L68 but it's hidden behind DEBUG. So to me it seems much easier to just make util-linux and log those extra messages than start putting them into dmesg. Can't we try that first?
