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.

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_stdinit,
