Hello, recently, syzbot evidently found an efficient way to fuzz UDF filesystem images creating subtly corrupted directories which were causing all sorts of trouble for UDF directory handling code. The code has already been rather convoluted so it was not really easy to plug the holes syzbot found. The patch set rewrites udf directory handling code to a more managable codebase and as an side-effect also fixes several syzbot reports. I plan to queue the patches to my tree. Honza
