Variable Documentation

struct inode_operations ntfs_dir_inode_ops

Initial value:

= {
    .lookup = ntfs_lookup,  
}

Inode operations for directories.

struct export_operations ntfs_export_ops

Initial value:

= {
    .get_parent = ntfs_get_parent,  
    .fh_to_dentry   = ntfs_fh_to_dentry,
    .fh_to_parent   = ntfs_fh_to_parent,
}

Export operations allowing NFS exporting of mounted NTFS partitions.

We use the default ->encode_fh() for now. Note that they use 32 bits to store the inode number which is an unsigned long so on 64-bit architectures is usually 64 bits so it would all fail horribly on huge volumes. I guess we need to define our own encode and decode fh functions that store 64-bit inode numbers at some point but for now we will ignore the problem...

We also use the default ->get_name() helper (used by ->decode_fh() via fs/exportfs/expfs.c::find_exported_dentry()) as that is completely fs independent.

The default ->get_parent() just returns -EACCES so we have to provide our own and the default ->get_dentry() is incompatible with NTFS due to not allowing the inode number 0 which is used in NTFS for the system file $MFT and due to using iget() whereas NTFS needs ntfs_iget().
