LittleFS vs Little File System

I’ve integrated LittleFS into my application not using MBED, but am having some confusion about whether or not it’s thread safe. The reason for the confusion is that I thought that MBED OS Little FileSystem and https://github.com/ARMmbed/littlefs are the same thing. However the MBED documentation says that Little FileSystem is thread safe, while the github repo’s documentation does not.

Could someone please help me clear this up?
