NAME
VFS_MOUNT —
mount a filesystem
SYNOPSIS
#include
<sys/param.h>
#include <sys/mount.h>
#include <sys/vnode.h>
int
VFS_MOUNT(struct
mount *mp, char
*path, caddr_t
data, struct ucred
*cred);
DESCRIPTION
Mount a filesystem into the system's namespace.Its arguments are:
- mp
- Structure representing the filesystem.
- path
- Pathname where the filesystem is being mounted.
- data
- Filesystem specific data. This should be read into the kernel using copyin(9).
- cred
- Pointer to a struct ucred for user credentials checking.
This is called both to mount new filesystems and to change the
attributes of an existing filesystem. If the
MNT_UPDATE flag is set in
mp->mnt_flag then the filesystem should update its
internal state from the value of mp->mnt_flag. This
can be used, for instance, to convert a read-only filesystem to read-write.
It is also used by
mountd(8) to update the NFS export information for the
filesystem.
If the MNT_UPDATE flag is not specified,
then this is a newly mounted filesystem. The filesystem code should allocate
and initialize any private data needed to represent the filesystem (it can
use the mp->mnt_data field to store this
information).
