New stuff up in git

New stuff up in git

[Kent Overstreet]

I just finished updating both the bcache (off 2.6.34) and the
bcache-3.1 branches with the latest stable code.

Also got cgit set up and working, finally. Need to stick a link in the
wiki to it..

http://evilpiepirate.org/git

I still haven't figured out how to pack a git repository so cloning it
doesn't take > 80% of my linode's ram, but cloning works for me so I'm
done screwing with it for now.

The bcache branch compiles but hasn't been tested. I don't expect any
issues though, it's pretty close to what I normally develop/test on.

The bcache-3.1 branch still doesn't quite compile, but it's pretty
close - I'm try and get a working version pushed tomorrow, I did boot
a linux 3.1 + bcache kernel at one point...

I was able to make a clone by cloning Linus' repository on github,
then adding your repository as a remote then fetching, in case that
helps anyone.

I made a patch using the bcache-3.1 branch that does apply to the 3.0
tree as well FYI. Haven't attempted to compile it yet but will do in a
bit, see what happens. Do you need to set CONFIG_BCACHE=y in the
kernel config?

Yeah, that's one way around that issue. I really should just flip on
cloning over http... git's memory consumption is kind of infuriating.

I think the block layer's been fairly quiet since ~2.6.39 or .38, the
patches in the bcache-3.1 tree should move back that far without any
issues. But it won't compile on any of them just yet.. I think the stuff
that's left is trivial but it's late and I have to be up too early.

And yeah, you'll need CONFIG_BCACHE.

I have to say I haven't really encountered memory issues with it when
hosting, but then I haven't tried hosting anything as large as the
kernel.

Well I shall look forward to what patches tomorrow brings in that
case. Thanks a lot!

Hi Kent,

it would be really helpful if kernel patches (I mean diffs) would be provided.
If it wasn't necessary to clone the whole repo to get to the bcache,
instead only download kernel source and apply a patch, then probably
some more people would be encouraged to try bcache and report possible
bugs and/or test performance.
I know I would do it.

With some automatic/scripted patch generation and publishing it would
really require minimal work from your part and probably provide much
more feedback.

Tools repo is not problematic in this respect. It is small.

Just a thought and a recommendation:)

b.

Re: New stuff up in git

Sorry if this is a dumb question, is bcache-3.1 an update to bcache for 
kernels 3.1+

I ask because I dumbly merged bcache onto the v3.0 tag today since I 
want to have a play with bcache

It's the current bcache code rebased onto 3.1, yeah.

Heh. Did you get it to compile/boot? the bcache-3.1 branch isn't
_quite_ that far.

I did get to compile and boot, although I took the bcache branch and not 
bcache-3.1 (when I say compile it wont compile if I have debugging 
turned on, but I am ignoring that :S)

Nice. If you want to push/email your changes I'll merge them into the
bcache-3.1 branch.

Now if only I had some up to date documentation... :)

Re: New stuff up in git

[Greg Bowyer]

Sorry for the delay I was away over the weekend, my changes (minimal as 
they are) are on github

https://github.com/GregBowyer/linux-bcache

I didn't spend much time working out compile errors if I put on 
debugging, they should be pretty easy to fix, I just wanted to play
I also didn't realize that I needed to format the backing device 
separate to the cache device, I have not had a chance to fully test 
everything, I will try it out over the next few days.

Do you want me to give this a more serious look over ?

Nah, don't worry about spending any extra time on it. I've got a bunch
of minor stuff to fix and fixes to merge in right now, hopefully
should have some of that done tonight.
