Suggested tweak to the commit message:

Update the super block operations to support the new fs_context-based
mount API, full read-write support including ->sync_fs, and file system
shutdown support.

Update ntfs_statfs() to provide statistics using atomic counters for free
clusters and MFT records.

Introduce a background workqueue for asynchronous free cluster
calculation (XXXXX: please add a sentence here why is is useful / needed)

Implement ntfs_write_volume_label() to allow changing the volume label.

With that:
