Here is an updated version of my original patch to fix OFD locking.
The difference between this and the my original version is that
I added extra parenthesis to make it easier to read as per Jeff's suggestion
and I added a check if the files were the same from Pavel's review.

This is based on my original submission and not Paulo's patch.
I think Paulo's patch is primising since it will also refactor the code
to be easier to understand, but that is for a later patch.
This patch is smaller in the changes it does to the difficult parts and
I think less risky for changing behavior.
Something like Paulos patch is probably worthwile to refactor and simplify
the code at a later stage.


I tested this on-top of the current sfrench/for-next using xfstest.
No new regressions as far as I can tell.
