Constant virtual_fs::host_fs::DEFAULT_BUF_SIZE_HINT

const DEFAULT_BUF_SIZE_HINT: usize = _; // 8_192usize

Default size for write buffers.

Chosen to be both sufficiently large, and a multiple of the default page size on most systems.

This value has limited meaning, since it is only used for buffer size hints, and those hints are often ignored.
