.In sys/kernel.h
.In sys/module.h
.In sys/mount.h void VFS_SET "struct vfsops *vfsops" "fsname" "int flags"

DESCRIPTION

VFS_SET creates a
.Vt 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.
