Subject: [RFC PATCH V4 0/2] Btrfs: get/set mounted filesystem label support
Content-Type: text/plain; charset=ISO-8859-1
Sender: linux-btrfs-owner@vger.kernel.org
List-ID: <linux-btrfs.vger.kernel.org>

Hello,

This is an improved tiny patch set to add get/set the label upon a mounted
file system via ioctl(2).

I'd like to add the Signed-off-by with Anand for the credit since He has posted a
similar patch set a few month ago.


Changes of V4->V3:
- Add a new ioctl to fetch the label of a mounted file system.
- Replace "struct btrfs_ioctl_fs_label_args" with "char label[BTRFS_LABEL_SIZE]".
- ioctl(2) number changed from 50 to 53/54. I'll update the btrfs wiki page with regard to
  the number allocation to reflect this change if it is ok.


The old versions can be found at:

v3:

v2:

v1:

Thanks,
-Jeff
