From: Dave Chinner <dchinner@xxxxxxxxxx>
Source kernel commit: 2beb7b50ddd429f47b6cabd186b3102d2a6aa505
The vast majority of these wrappers are now unused. Remove them
leaving just the small subset of wrappers that are used to either
add feature bits or make the mount features field setup code
simpler.
