I put fixed patches (including the one against 2.6.15) on our ftp-server.

Perhaps it got fixed when migrating to the new code
for reiser4/vfs interface (Peter used the old one).

Apologies if this gets posted twice, I saw there was a list malfunction so
posting it again as my previous message never showed up.
Hi Edward,
I've just tested the newer patch against 2.6.15.4, and have found a bug when
using `cat bmap` in a directory.
$ cd testdir/....
$ cat bmap

Hi,
The current reiser4 patch for 2.6.15 doesn't seem to have support for pseudo
files. Is there a seperate patch elsewhere for adding this functionality
back in?
Regards,

Hello,
there are metas-patches on our ftp-server, although it is
not fresh. I'll advance it on the next week, ok?

Attached is a patch for 2.6.15 that I threw together from the 2.5.14-rc5-mm1
patch on the ftp server. Please check if it's ok.
Have a few problems/observations:
1. I get an oops if I try `cat items`. Reproduced with 2.6.14-rc5-mm1 and
it's patch on the namesys ftp server, so it's been there for a while.
$ cd test/....
$ cat items

3. At http://www.namesys.com/v4/pseudo.html there is a _pagecache_ pseudo
file that seems to be missing. There is also a pseudo file called _new_
that isn't described there. What is it for?
4. I couldn't reproduce the bash-crashing bug described at
http://pvh.ca/trac/wiki/Reiser4Bugs
Has it been fixed?
