This particular kernel contains changes to the following:

- binder bugs, i.e. leaks, API misuse
- lowmem killer logic errors
- scheduler, i.e..spurious wakeups, "bouncing cow", fair scoring
- vm subsystem changes to oom killing, google lowmemkiller
- kswapd wasting CPU time no longer occurs
- cpufreq microoptimizations (wakeups, useless computation), interactive governor updated to latest version from msm-kernel for 3.10 Google Wear

Credits:

Kernel forked from work of another xda member. That's documented in github project itself, and revision history.

Changes come from Torvalds tree, msm and common. The kswapd fix comes from a google search. You can look for "contention_wait" yourself to note the source.

Pull requests and forks welcome. So are quality well-researched bug reports. Feature requests, only if sensible and educated.

First post includes a link to the sources. Given an ARM cross-compiler that can build the kernel, it's a matter of repacking initrd and flashing.

Unless you suffer from the kswapd issue, there's little point. Fixes included aren't something you'd notice after using the software briefly.

My intention is to make available the changes. Whether they're given attention or are reviewed at all, doesn't depend on me really.

Please note, you don't have to fork the repository on github to follow the changes.

If you in fact never compile kernels yourself you're not my intended audience.

Still, getting to know C is always the first step toward any serious Linux/Unix hacking.

Kernel stuff isn't any different than others. There are some rules to follow, but this is true of userland code, too. Documentation often says "don't do this and that". Just like with kernel API.
