I'm trying to learn more about Linux and its file system and I'm stuck on understanding the difference between the ext3 and ext2 file systems with regards to system calls during file creation and modification.

I understand the fundamental differences between ext2 and ext3 up to this point.

Could someone point me in the right direction.

I do not understand what you are really asking but answer is probably:

There is supposed to be no difference between filesystems. Syscalls and VFS are filesystem-agnostic. POSIX standard defines most of what file operations do, as far as stat fields are concerned, thus defining when and how atime alike fields are updated. That said, filesystems have their own quirks, but probably not regarding what you ask.
