It used to be the case, that the cache was flushed early enough to make the following flush all data for a file-system: # cd /mount/point # umount /mount/point The unmount fails, since PWD is within the file-system to be unmounted. But the cache has already been flushed by then ... If the question was not about flushing the cache e.g. for benchmarking purposes, then I'm not sure that a direct equivalent to the Linux command exists (not knowing Linux and the exact semantics of drop_caches in the original message).
