Hi Linus,
I had missed that for two of the patches in my last pull, we had
included different fixes during 3.7. My for-linus has them reverted:

The (u64) cast was presumably to keep from losing high bits during the
shift. page_offset() already has that cast internally and returns
loff_t, which is always long long. I think that you can d

It's really easy to get this warning.
In my other testing codes, got the same issue again.

Hi Eugene,
You may want to port up-to-date User-Mode-Linux to the ARM platform (at least
yours), and then run your custom UML-powered file server with support for all
the improved features of BTRFS per Linux 3.7.
Hope this helps.
Regards,
Valentin

This patch fixes two bugs:
When we do not assigne a device id for the resizer,
- it will only take one device to resize, which is supposed to apply on
all available devices.
- it will take 'id 1' device as default, and this will cause a bug as we
may have removed the 'id 1' devi

Hello,
Per David's comments upon v6, I missed a check up against the return value of
btrfs_end_transaction for
btrfs_ioctl_fs_setlabel(), it was fixed in this version.
v7->v6:
- take care of btrfs_end_transaction() in btrfs_ioctl_fs_setlabel() rather than
keeping silence.
