Subjectmemleak-deluxe outputs 2.0.33pre8
The last two posings of this mail got lost after vger has acknowledged
their arrival. Third try.

=Subject: memleak-deluxe outputs 2.0.33pre8

I've been looking for lost memory during the last few days (I can't
get through the code in fs/buffer.c...). Now that the server has
an uptime of 8 days, the data accumulates and may be useful for
the public. Here are the outputs from Ingo's memleak-deluxe-patch,
running in 2.0.33; posting 26000 lines is messy, so have a look at it
at
ftp://ftp.uni-freiburg.de/pub/linux/misc/memleak/
or nfs:
ftp.uni-freiburg.de:/ftp/pub/linux/misc/memleak

if you're interested. All used files are there. Online dump of data
via inetd is possible upon request.

There is the kernel tree, the used patches and the output from
/proc/memleak along with /proc/meminfo. The data is being updated
every 10 minutes into a time-stamped file from now on. I found out
that mmap()ping the files in proc using tar is not a good idea... :-)

Please drop me a note if you're using the stuff. I intend to reboot
the machine some day this week due to a minor memory upgrade.
By the way: The box had no problem whatsoever. Fully stable in kernel
and userland.
