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 struct thread *td);

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:

Fa mp: Structure representing the file system.
Fa td: Thread which is mounting 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 Fa mp->mnt_flag then the file system should update its internal state from the value of Fa 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 Fa mp->mnt_data field to store this information).
