VFS_MOUNT - mount a file system
The arguments it expects are:
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).
