Jan Kara f26391f2a7 udf: Avoid using stale lengthOfImpUse ... BugLink: https://bugs.launchpad.net/bugs/1980277 commit c1ad35dd05 upstream. udf_write_fi() uses lengthOfImpUse of the entry it is writing to. However this field has not yet been initialized so it either contains completely bogus value or value from last directory entry at that place. In either case this is wrong and can lead to filesystem corruption or kernel crashes.
