Hi Linus,
In this round, as Ted pointed out, fscrypto allows one more key prefix given by
filesystem to resolve backward compatibility issue. Other than that, we could
fix several error handling flow by introducing fault injection facility. We've
also achieved performance improvement in some workloads as well as a bunch of
bug fixes.
Could you consider pulling the below patches?
Thanks,

f2fs: fix to update dirty page count correctly (2016-05-20 14:55:41 -0700)
----------------------------------------------------------------
Enhancement
- fs-specific prefix for fscrypto
- fault injection facility
- expose validity bitmaps for user to be aware of fragmentation
- fallocate/rm/preallocation speed up
- use percpu counters
Bug fixes
- some inline_dentry/inline_data bugs
- error handling for atomic/volatile/orphan inodes
- recover broken superblock
