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).
