NAME¶
VFS_MOUNT — mount a file systemSYNOPSIS¶
#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.
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).
