VFS_MOUNT - mount a file system


In sys/param.h In sys/mount.h In sys/vnode.h Ft int Fn VFS_MOUNT struct mount *mp


The Fn 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.

The Fn 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).
