/*
* 2.6.30 API change
- * To ensure good performance preferentially use the physical block size
- * for proper alignment. The physical size is supposed to be the internal
- * sector size used by the device. This is often 4096 byte for AF devices,
- * while a smaller 512 byte logical size is supported for compatibility.
- *
- * Unfortunately, many drives still misreport their physical sector size.
- * For devices which are known to lie you may need to manually set this
- * at pool creation time with 'zpool create -o ashift=12 ...'.
- *
- * When the physical block size interface isn't available, we fall back to
- * the logical block size interface and then the older hard sector size.
+ * Change to make it explicit there this is the logical block size.
