     VFS_SET — set up loadable file system vfsconf


     #include <sys/param.h>
     #include <sys/kernel.h>
     #include <sys/module.h>
     #include <sys/mount.h>

     VFS_SET(struct vfsops *vfsops, fsname, int flags);


     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

     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.

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


      * 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);


     jail(2), jail(8), DECLARE_MODULE(9), vfsconf(9), vfs_modevent(9)
