Al, any comments?
Resending this after adding Reviewed-by/Acked-by tags.


From previous version:-
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.
