There is no difference betweem tmpfs and shm. tmpfs is the new name for shm. shm stands for SHaredMemory. See: Linux tmpfs. The main reason tmpfs is even used today is this comment in my /etc/fstab on my gentoo box. BTW Chromium won't build with the line missing: # glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for # POSIX shared memory ...


There's no difference between shm and tmpfs (actually, tmpfs is only the new name of former shmfs). hugetlbfs is a tmpfs-based filesystem that allocates its space from kernel huge pages and needs some additional configuration afford (how to use this is explained in Documentation/vm/hugetlbpage.txt).
