Yes, this is a problem. There is a fundamental flaw in the series surrounding commit a0461d15d75c. In discussion with Eric it was decided a different approach was needed and I'm holding back on posting an updated series because I was worried something like this might happen and didn't want to make matters worse. I definitely don't want this series to go to the Linus tree and it would be great if you could drop it from the next tree. Eric's patch should then apply without change. I had asked Andrew to drop the series but he must have missed my request. And I thought they had already been dropped but I must have been looking at an incorrect branch. I'll need to look at the akpm repo. again. In the meantime all I can offer is the patch names corresponding to the descriptions. They are: fs-make-is_local_mountpoint-usable-by-others.patch fs-add-have_local_submounts.patch autofs-make-mountpoint-checks-namespace-aware.patch fs-remove-unused-have_submounts-function.patch Sorry for the inconvenience.
