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

NAME
     VFS_SET -- set up loadable file system vfsconf

SYNOPSIS
     #include <sys/param.h>
     #include <sys/kernel.h>
     #include <sys/module.h>
     #include <sys/mount.h>

     void
     VFS_SET(struct vfsops *vfsops, fsname, int flags);

DESCRIPTION
     VFS_SET() creates a vfsconf structure for the loadable module with the given vfsops, fsname and flags, and declares it by calling
     DECLARE_MODULE(9) using vfs_modevent() as the event handler.

     Possible values for the flags argument are:

     VFCF_STATIC      File system should be statically available in the kernel.

     VFCF_NETWORK     Network exportable file system.

     VFCF_READONLY    Does not support write operations.

     VFCF_SYNTHETIC   Pseudo file system, data does not represent on-disk files.

     VFCF_LOOPBACK    Loopback file system layer.

     VFCF_UNICODE     File names are stored as Unicode.

     VFCF_JAIL	      Can be mounted from within a jail if security.jail.mount_allowed sysctl is set to 1.

     VFCF_DELEGADMIN  Supports delegated administration if vfs.usermount sysctl is set to 1.

PSEUDOCODE
     /*
      * fill in the ones we use, and use the vfs_std for the rest.
      */
     static struct vfsops myfs_vfsops = {
	     myfs_mount,
	     vfs_stdstart,
	     myfs_unmount,
	     myfs_root,
	     vfs_stdquotactl,
	     myfs_statfs,
	     vfs_stdsync,
	     vfs_stdvget,
	     vfs_stdfhtovp,
	     vfs_stdcheckexp,
	     vfs_stdvptofh,
	     vfs_stdinit,
	     vfs_stduninit,
	     vfs_stdextattrctl,
     };

     VFS_SET(myfs_vfsops, skelfs, 0);
