I feel like I have to reply to this :-) First of all, thank you. But unfortunately my knowledge of core kernel is quite limited, I pick up some bits here and there by reading the code, but this is too little and sometimes my deductions are wrong. Another thing is very limited time. I do like fixing code, but I rarely have time and when I have it must be something very interesting and important to me. This time it is interesting :-) Because I actually use UDF quite a lot, I use DVD-RAM media for various archival and data transfer purposes, and sometimes there is some unusual case. I also try to keep up with FreeBSD development as much as possible, so sometimes there are new issues after upgrades. So, thank you again, but please think of me as of occasional patch submitter. -- Andriy Gapon
