Linux Ever year, Linus Torvalds goes on vacation to Australia, during which he usually also visits linux.conf.au. During his stay this year he gave an interview to ComputerWorld, in which he talked about the success of point releases and the important topic of file systems in Linux, which is quite an active field today with ext4 and Btrfs. He also gave some insights into why he switched away from KDE, moving to GNOME instead, and he shares his thoughts on Windows 7.

What does Linus know about btrfs and ZFS?

"To some degree Btrfs does what ZFS does. Some uni ran ZFS as a module in Linux so using it with Linux can be done. The biggest thing Sun did with ZFS is they were good with PR and marketing."

From http://btrfs.wiki.kernel.org/index.php/Main_Page:
"Btrfs is under heavy development, and is not suitable for any uses other than benchmarking and review. The Btrfs disk format is not yet finalized, but it will only be changed if a critical bug is found and no workarounds are possible."

Above is pure evidence that Linus does not know so much as he should about even btrfs. Trying to compare fully functional storage subsystem like ZFS (which integrates classic FS and VM and part of BIO layers on one subsystem) with something like only plot of the new FS (which keeps all in classic way of thinking about storage) is very naive.

btrfs it is nothing that only next example NIH syndrome (Not Invented Here). Head one of biggest FOSS project shows next time only pure incompetence on trying compare btrfs and ZFS.

Just because an engineer is proficient in their background with kernels, what makes you think they are remotely well-versed in filesystems?

Specialties are quite common, especially in Computer Science.

If you are proficient engineer proficient with kernel background and if you really saw ZFS in action more than few minutes you should be able distinguish between classic FS and something which is not.
I'm not talking about Linus professional background but only about what he know and what he doesn't know in context his public speech.
Simple he talks about things he doesn't know and this is completely unprofessional behaviour.
