fscking tmpfs, if it does make sense, can't ever be done from the
userland; fsck_tmpfs could, in theory, only instigate the kernel file
system driver to "do something" and probably return some sort of simple
status result - it would be much harder to do any kind of superuser
interaction like the "normal" fsck programs do.
While there could, in theory, be some kind of scrubbing function in the
kernel module that traverses the in-memory structures, I doubt it would
make sense - I suspect the system would crash very soon if a memory
corruption or a bug that mangles the structures existed. Possibly
defragmentation could be useful, but I don't know enough about tmpfs to
say for sure.
