VFS(9)							   BSD Kernel Developer's Manual						    VFS(9)

NAME
     VFS -- kernel interface to file systems

DESCRIPTION
     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.
