Linux Linux kernel 3.4 has been released. New features include several Btrfs updates: support of metadata blocks bigger than 4KB, much improved metadata performance, better error handling and better recovery tools; there is also a new X32 ABI which allows to run programs in 64 bit mode with 32 bit pointers; several updates to the GPU drivers: early modesetting of Nvidia Geforce 600 'Kepler', support of AMD RadeonHD 7xxx and AMD Trinity APU series, and support of Intel Medfield graphics; support of x86 cpu driver autoprobing, two new device-mapper targets, several perf improvements such as GTK2 report GUI and a new 'Yama' security module. Here's the full list of changes.

Btrfs is probably stable enough to use, but its recovery tools (the last time I checked) were not up to par with the recovery tools for other file systems. Plus Btrfs in my tests is quite a bit slower than ext4. You're probably better off using ext3 or ext4 for now, until Btrfs performance and reliability have been proven.

I used btrfs on my Ubuntu 11.04 system (just as a trial) and it totally bogged down I/O operations on my system.

Only figured it out that it was actually the case when doing a fresh install for the 12.04

So you can try it if you want (and you probably should since there might be some hardware issues related to that) but just remember that in case something funky happens to revert to ext3 or 4 and check if you have same issues.

Unfortunately, no. I've played with it on disposal data and results were a bit frightening... It will get there, but right now it's not stable for production use.
