Matthew Wilcox in [1] suggested that it will be a good idea to define some missing API instead of directly using i_rwsem in filesystems drivers for lock/unlock/downgrade purposes. This patch does that work. No functionality change in this patch. After this there are only lockdep class of APIs at certain places in filesystems which are directly using i_rwsem and second is XFS, but it seems to be anyway defining it's own xfs_ilock/iunlock set of APIs and 'iolock' naming convention for this lock.
