Amended the commit message, and actually squashed 2 patches to preserve
bisectability.

I've pushed this to the master branch.

I've also re-based your 'joel' branch on top of the master branch.

Your old branch is saved in 'joel_old'.

I did this because there were minor a minor conflict with other UBIFS
changes, so I thought it makes sense to rebase now.

Some tips.

1. save all your changes.
2. checkout the 'joel' branch
3. git fetch -f
4. git reset --hard origin/joel

This will let you update to the latest joel.

git checkout -b jeol_old origin/joel_old

will give you your old stuff.

Yes, sorry, I told you I won't rebase but then I noticed small conflicts
and decided that it is better if you are up-to-date. If you are unhappy
- let me know and I'll return you to the old stuff and will apply this
patch there.

Thanks!
