So, How do you find out or see which filesystems are supported by the Linux kernel? The answer is simple. Use
/proc/filesystems file. It is the file used to detect filesystems supported by running kernel. You can quickly run or to display the list of all supported file system. nodev indicates that the file system is not associated with a physical device such as /dev/sdb1. If you see ext3 or vfat, it means you will be able to mount ext3 and vfat based file systems.
