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
TheVFS_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).
