From: Wedson Almeida Filho <walmeida@xxxxxxxxxxxxx>
Introduce a basic sample that for now only registers the file system and
doesn't really provide any functionality beyond having it listed in
`/proc/filesystems`. New functionality will be added to the sample in
subsequent patches as their abstractions are introduced.
