- This is the new set of userspace utilities created by Samsung for using the exfat file system inside of the Linux kernel as of version 5.7 (we are still on 5.6 for the moment though) and later. It provides a big performance boost compared to the current fuse driver that existed before this and many other positives due to being the official driver from Samsung. Anybody with an exfat drive could possibly want this.
- Yes it is GPLv2
This basically replaces exfat-utils, however we would still need that for the LTS kernel of course...
