Linux: Slab Defragmentation

"Slab defragmentation is mainly an issue if Linux is used as a fileserver and large amounts of dentries, inodes and buffer heads accumulate," Christoph Lameter explained when posting the fifth version of his patchset. He continued,"in some load situations the slabs become very sparsely populated so that a lot of memory is wasted by slabs that only contain one or a few objects. In extreme cases the performance of a machine will become sluggish since we are continually running reclaim. Slab defragmentation adds the capability to recover wasted memory."

Keep your laptop and PC in Unison

I usually carry my laptop everywhere and do work on it, but I do also need to work at my desktop PC, so I need to synchronize the files on the two machines.

Linux: Continuing Dual-Licensing Discussions

Discussion continues on the Linux Kernel mailing list about the legality and morality of re-licensing BSD/GPL dual-licensed code under only the GPL. Alan Cox replied to Theo de Raadt's comments suggesting he was encouraging people to break the law, "re-read my email and then apologize. I do question the .h files where they are BSD licence and no changes were made to the work. I also point out that the dual licence on that code appears to give permission to distribute under one of those licences by choice." In response to Theo's request that code be shared both ways rather than converted to a sole GPL, "that's about the first thing I would agree on - its somewhat rude and not something I personally would usually choose todo."
