hrmph, CC to members only list removed.
What makes you think it is members only?!? NTFS-dev is not members
only at all. It is moderated which is a very different thing. Most
list members have to be approved for posting, too... And the only
reason it is moderated is spam filtering. We delete 99.9% of emails
going to the list by hand as moderators because they are all spam.
That means the list and the list archives only contain NTFS related
messages and not thousands of posts trying to sell you pills and what
not...
Best regards,
Anton

Greetings,
I've stumbled across a 2.6.22->2.6.23 regression. First md5sum
access
of an empty NTFS file leads to kernel I/O error gripe, a second
access
leaves md5sum hung. 2.6.22.10 has no trouble accessing this file.
Looking at the 22->23 diff, I don't see a quick and dirty stab
candidate, and since I'm preparing for a 5 week separation from my
box
<twitch>, I doubt I'll have time to do a bisect. /me punts.
