Backporting bugfixes

Backporting bugfixes

[Pavel Roskin]

Hello!

I have noticed that there have been important fixes for btrfs in the  
mainline Linux git repository.  However, there is just one btrfs fix  
in Linux 3.12.5 after 3.12.

I think it's important to submit all serious bugfixes to the stable  
kernels.  It would protect users against data corruption and improve  
the image of btrfs as a serious filesystem that can be trusted at  
least with semi-important data.

Hi Pavel,

We do tag some commits for stable, but Dave Sterba actually just sent a
request to the stable tree to pull in a few more.

That's great news!  Thank you for a quick reply!

In fact, here's the stable-queue request.

<http://permalink.gmane.org/gmane.linux.kernel.stable/73711

(It was cross-posted to both the btrfs and stable lists. =:^)

That said, while btrfs bugfixes are generally being submitted to stable 
when appropriate, as with all stable-tree patches since they aren't 
eligible for stable until they've hit the development kernel, the fastest 
(non-btrfs-next or direct-off-the-list) way to get them is to run either 
that development kernel.

Which isn't entirely inappropriate in any case, given that while the 
btrfs kconfig warnings were turned down some in 3.12, it's still under 
heavy development such that users who choose to run it are choosing to 
run a not yet fully stable filesystem, and if they're already risking 
their data on that, they might as well run a full development kernel too.
