In addition * the cifs mount must be mounted with the "serverino" option (ie use stable * server inode numbers instead of locally generated temporary ones). * Although cifs inodes do not use generation numbers (have generation number * of zero) - the inode number alone should be good enough for simple cases * in which users want to export cifs shares with NFS. The decode and encode * could be improved by using a new routine which expects 64 bit inode numbers * instead of the default 32 bit routines in fs/exportfs * */ #include <linux/fs.h> #include <linux/exportfs.h> #include "cifsglob.h" #include "cifs_debug.h" #include "cifsfs.h" #ifdef CONFIG_CIFS_NFSD_EXPORT static struct dentry *cifs_get_parent(struct dentry *dentry) { /* BB need to add code here eventually to enable export via NFSD */ cifs_dbg(FYI, "get parent for %p ", dentry); return ERR_PTR(-EACCES); } const struct export_operations cifs_export_ops = { .get_parent = cifs_get_parent, /* Following five export operations are unneeded so far and can default: .get_dentry = .get_name = .find_exported_dentry = .decode_fh = .encode_fs = */ }; #endif /* CONFIG_CIFS_NFSD_EXPORT */ |
