Based on Dan's comment on patch 1, it may be sufficient to just include
storage_driver.h instead, which may affect the function names you call.
 But the conversion looks sane - instead of calling direct file system
syscalls, we now call polymorphic storage calls, and let the storage
driver manage whether it is a syscall or a gluster library call (or any
future other backends that also add in their driver).

ACK.
