zx::result<> Readblk (blk_t bno, void * data)Raw block read functions.
These do not track blocks (or attempt to access the block cache)
NOTE: Not marked as final, since these are overridden methods on host,
but not on __Fuchsia__.

zx::result<std::unique_ptr<Bcache>> Create (std::unique_ptr<block_client::BlockDevice> device, uint32_t max_blocks)This factory allows building this object from a BlockDevice. Bcache can take ownership of the
device (the first Create method), or not (the second Create method).

zx::result<> SetOffset (off_t offset)Tell Bcache to look for Minfs partition starting at |offset| bytes
Defined at line 100 of file ../../src/storage/minfs/bcache_host.cc
zx::result<> SetSparse (off_t offset, const fbl::Vector<size_t> & extent_lengths)Tell the Bcache it is pointing at a sparse file
|offset| indicates where the minfs partition begins within the file
|extent_lengths| contains the length of each extent (in bytes)

void Pause ()Blocks all I/O operations to the underlying device (that go via the RunRequests method). This
does *not* block operations that go directly to the device.

uint32_t Maxblk ()Returns the maximum number of available blocks,
assuming the filesystem is non-resizable.
