UBIFS changes for 2.6.39

Hi Linus,

please pull UBIFS changes. Note, I usually keep UBI and UBIFS changes in separate trees, but this time I have a couple of UBI changes in the UBIFS tree because they have hard dependency with UBIFS fixes.

The following changes since commit 3c0eee3fe6a3a1c745379547c7e7c904aa64f6d5:
