Description

The ZFS range locking code in zfs_rlock.c/h depends on ZPL-specific data structures, specifically znode_t. However, it's also used by the ZVOL code, which uses a "dummy" znode_t to pass to the range locking code.

We should clean this up so that the range locking code is generic and can be used equally by ZPL and ZVOL, and also can be used by future consumers that may need to run in userland (libzpool) as well as the kernel.
