Can you reproduce it with 2.5.66?

sb->s_export_op->find_exported_dentry is NULL in reiserfs_decode_fh, well. In fact we never set this field at all. What is supposed to be there, anyway? I guess following patch should fix the problem.
In fact I guess somebody should put find_exported_dentry() declaration to include/linux/fs.h or something like that. Also absolutely the same problem must exist if you try to export fat filesystem.
Bye, Oleg
