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.
