I've kind of been sitting on them until the dcache_lock breakup and rcu path-walk has had some time to be shaken out. The patch =D1=95et is pretty much unchanged from the last round of review last last year - all I've done to bring it up to date is forward port it and run it through some testing on XFS and ext4. I know it's late in the .39 merge window, but I hope you'll consider it if the patches are still acceptable(*). Otherwise I'm happy to take the time to get it right for .40. Cheers, Dave.
