You can follow <a href="http://www.linuxhq.com/patch-howto.html" rel="nofollow">these instructions</a> for example. Generally, from the <em>/usr/src</em> directory you will launch something like "<em>gzip -d -c patch.gz | patch -p0</em>" or "<em>patch -p0 < patch</em>".

Is there anywhere where it is clearly laidout? I tried using the wiki before but it doesnt really tell you how to apply the patch. Thanks! Where did you get the steps to building a Reiser4 kernel.

If you want to see what is the actual space occupied/free on the drive/partition use "<em>df</em>". To check the real dimension of your files use “du -s <directory>“. If you want to see what is the actual space occupied/free on the drive/partition use “df“.

They are copied uncompressed somewhere to increase speed and efficiency and then moved/compressed later when there are some spare CPU cycles and if it has been established that the content is compressible. It's a pretty amazing feature, don't you think? :) If you really want it to be compress everything right away use compressMode=force, but based on my tests I would not recommend it It is normal, since you selected the compressMode “ultimately”, things

Everything works fine except the compression. I created the Reiser4 partition with sudo mkfs.reiser4 -o create=ccreg40,compress=gzip1,compressMode=ultim,cluster=8K /dev/sda4. When I copy a folder to this partition (/mnt), its size does not shrink,e.g. du -sm Documents/ /mnt/Documents/ 104 Documents/ 106 /mnt/Documents/ Hi Alessio, I did the same a few days ago also for the 2.6.31 kernel.
