/* Range lock constants.

* The storage format reserves the region from 0x7fffff00-0x7fffffff for
* locking and synchronization. Unfortunately, the spec doesn't say which bytes
* locking and synchronization. Because it reserves the entire block containing
* that range, and the minimum block size is 512 bytes, 0x7ffffe00-0x7ffffeff
* also cannot be used for any other purpose.
* Unfortunately, the spec doesn't say which bytes
* within that range are used, and for what. These are guesses based on testing.
* In particular, ends of ranges may be wrong.
