Several of my files have been doing this. I really noticed it when I

also started affecting documents I really care about.
I was wondering if I somehow have compression enabled. I didn't do it
on purpose! :)
If so, then definitely _no_.
I remember reading some comment about lzo being messed up and the
patches not included in mm yet? This is rc1-mm2 so I thought it might
be fixed, but I guess not.
Reiser4 in rc1-mm2 is already ported to the new lzo, however this library
is not used by default (unix-file) plugin.
Here is a snippet of a shell session showing the problem. It's a good
thing it didn't affect the OpenOffice format original!

As you can see, a copy shows the same problem. But adding "blah\n" to
the end makes the problem go away...
Yeah, I have also noted this badness: if file size % page size == 0,
then md5sum
complaints.
This is one more bug in new file_read: if vfs asks to read page out of
file size,
then fs should fill it by zeros (reiser4 returns -EINVAL instead). I'll
prepare the
patch a bit later..
Thanks,
Edward.
