  UBIFS: Implement ->migratepage() (2016-06-23 00:29:53 +0200)

----------------------------------------------------------------
This pull requests contains fixes for two critical bugs in UBI and UBIFS:
1. Fixes the possibility of losing data upon a power cut when UBI tries
   to recover from a write error.
2. Fixes page migration on UBIFS. It turned out that the default page
   migration function is not suitable for UBIFS.
