VFS(9)

VFS9

Kernel interface to file systems

Overview

Calls used to set or query file systems for settings or information.

File systems that do not implement a VFS operation should use the appropriate vfs_std function from src/sys/kern/vfs_default.c rather than implementing empty functions or casting to eopnotsupp.
