I've been keeping my own kernel patchset so far which included Reiser4. Did some tests with it against other "great" filesystems like ext4 and btrfs. I'd say there are some wins and loses against them, but so far I like how its gets a fairly bigger compression ratio compared to btrfs on... say... my whole Steam folder.
It still seems to suffer the same problem as Reiser3, though, slow mounting/unmounting.
I'm just an ordinary magician...
I actually used reiserfs once at work.
This thread is about Reiser 4.
Is there a prebuilt kernel for Arch available with reiser4 support?
Would like for example linux-ck kernel but with added reiser4 support, that would be awesome. Edward and the guys released the reiser4 patches yesterday to support 3.15.1.
