Kernel 3.19 and btrfs

Kernel 3.19 and btrfs

[Christian]

Hi,

I am relying on btrfs on a couple of work laptops now and things seems 
to work. I'm on Ubuntu 15.04. However, I've seen some horror stories 
about problems with btrfs on this kernel version. Since Ubuntu 15.04 
comes with 3.19 I'm a bit worried I am going to get in trouble at some 
point. I'm not technical enough to understand what the threat level is.

I have gotten addicted to subvolumes and snapshots so I would hate to 
have to go back to something else.

The bug has been fixed in 3.19.5. The 3.19(.0) release itself is not
affected either.

Ubuntu provide own patched kernel as i know.

Christian, if you have 3.19-15 kernel(shiped with 15.04 by default),
it has affected by deadlock bug while replaying journal.
But as i see in 3.19-16 (you can update) this issues has been fixed.

So, it you install latest updates, all must be okay.
