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.

        * fill in the ones we use, and use the vfs_std for the rest.
