NAME

       VFS_MOUNT — mount a file system

SYNOPSIS

       #include <sys/param.h>
       #include <sys/mount.h>
       #include <sys/vnode.h>

       int
       VFS_MOUNT(struct mount *mp);

DESCRIPTION

       The  VFS_MOUNT()  macro  mounts a file system into the system's namespace or updates the attributes of an
       already mounted file system.

       The arguments it expects are:

       mp    Structure representing the file system.

       The VFS_MOUNT() macro is called both to mount new file  systems  and  to  change  the  attributes  of  an
       existing  file  system.  If the MNT_UPDATE flag is set in mp->mnt_flag then the file system should update
       its internal state from the value of mp->mnt_flag.  This can be used, for instance, to  convert  a  read-
       only  file  system  to read-write.  It is also used by mountd(8) to update the NFS export information for
       the file system.

       If the MNT_UPDATE flag is not specified, then this is a newly mounted file system.  The file system  code
       should  allocate  and  initialize  any  private  data needed to represent the file system (it can use the
       mp->mnt_data field to store this information).
