Add I/O Read/Write Accounting
Because ZFS bypasses the page cache we don't inherit per-task I/O
accounting for free. However, the Linux kernel does provide helper
functions allow us to perform our own accounting. These are most
commonly used for direct IO which also bypasses the page cache, but
they can be used for the common read/write call paths as well.
