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	ker-
		      nel.

     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 allow.mount and
		      allow.mount._fsname_ jail	parameters are set.

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

     VFCF_SBDRY	      When in VFS method, the thread suspension	is deferred to
		      the user boundary	upon arrival of	stop action.

PSEUDOCODE
     /*
      *	Fill in	the fields for which we	have special methods.
      *	The others are initially null.	This tells vfs to change them to
      *	pointers to vfs_std* functions during file system registration.
      */
     static struct vfsops myfs_vfsops =	{
	     .vfs_mount	=    myfs_mount,
	     .vfs_root =     myfs_root,
	     .vfs_statfs =   myfs_statfs,
	     .vfs_unmount =  myfs_unmount,
     };

     VFS_SET(myfs_vfsops, myfs,	0);
