Changes of V4->V3 from the cover letter
- 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.

Cover letter [RFC PATCH V4 0/2] Btrfs: get/set mounted filesystem label support
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.
