Using a newer kernel is out of question here - I have to use the latest "Enterprise Linux" (CentOS 7) without patches.
Does that include using kernels from other CentOS repos?

The elrepo repository listed above has a mainline kernel that follows upstream stable releases, so no need for patching.
I wonder how safe it is to use these kernels, and whether it breaks the userland.
The older BTRFS utilities won't support the new features, but they should work OK for the previous functionality.
From the policy view, it somehow defeats the purpose of choosing an Enterprise Linux (with well-tested software in their own "kernel/userland universe") and then throwing out crucial parts of it.
The maintainers of the enterprise distribution should have been back-porting the BTRFS kernel code. But if you wanted to run the RHEL kernel it would probably have been a better idea to not use BTRFS. While I don't agree with people giving "always use the latest kernel for BTRFS" advice, I think that the minimum kernel version should be something a lot newer than that. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
