These tests perform common FS operations in various ways: - open/close - read/write - create/delete - read/change size - seek/tell - memory-mapped read/write - copy directory in different ways Tests use both direct syscalls and stdio wrappers (FILE). To run, call `make test` in `LibOS/shim/test/fs`.
