Today I discovered another linux kernel patchset/fork that attempts to bring many features not in mainline together, called pf-kernel.

Quoting from its website:

“pf-kernel is another Linux kernel fork, that provides you with new useful features, that are not merged into mainline. It’s not based on any existing Linux fork or patchset, but some parts of Zen kernel may be merged if there’s no official release of needed patch. The name of this fork is not connected with BSD Packet Filter. «pf» means «post-factum» in the short form.”

At this point the latest patchset includes the following:
* mainline update: 2.6.35.4
* -ck patchset (BFS included)
* BFQ
* TuxOnIce
* LinuxIMQ

Its main advantage over other forks seems to be that it’s regularly updated

I’m using it on my main system without any issues, so I added it to Gentoo’s tree:

* sys-kernel/pf-sources
Available versions:
(2.6.31_p9) (~)2.6.31_p9!b!s
(2.6.32_p16) (~)2.6.32_p16!b!s
(2.6.33_p4) (~)2.6.33_p4!b!s
(2.6.34_p7) (~)2.6.34_p7!b!s
(2.6.35_p7) (~)2.6.35_p7!b!s
