159 * The vnode infrastructure is being reorgranized. Most reference-related
160 * fields are locked by the BGL, and most file I/O related operations and
161 * vnode teardown functions are locked by the vnode lock.
162 *
163 * File read operations require a shared lock, file write operations require
164 * an exclusive lock. Most directory operations (read or write) currently
165 * require an exclusive lock due to the side effects stored in the directory
166 * inode (which we intend to fix).
167 *
168 * File reads and writes are further protected by a range lock. The intention
169 * is to be able to break I/O operations down into more easily managed pieces
170 * so vm_page arrays can be passed through rather then UIOs. This work will
171 * occur in multiple stages. The range locks will also eventually be used to
172 * deal with clustered cache coherency issues and, more immediately, to
173 * protect operations associated with the kernel-managed journaling module.

175 * NOTE: The vnode operations vector, v_ops, is a double-indirect that
176 * typically points to &v_mount->mnt_vn_use_ops. We use a double
177 * pointer because mnt_vn_use_ops may change dynamically when e.g.
178 * journaling is turned on or off.
