Sorry, I just saw this PR. This one is strange because emubd should be covered by this mbedignore file?
https://github.com/ARMmbed/mbed-os/blob/master/features/storage/filesystem/littlefs/.mbedignore

I'm glad it's fixed but do we know why it wasn't being picked up?

Oh, I missed that. Should have thought of it, as I've never seen such a problem. Can revert the change and investigate it a bit more with the reporter.

Don't worry about reverting (sorry if I'm getting this too you too late). I'm about to clobber the change with a minor release of littlefs (1.7).
