I'm not pulling this until the mess with the NFS tree is sorted out.
Apparently you rebased your (public!) VFS tree, and now half of your
old pre-rebase patches are in the NFS tree.
Rebasing public trees IS NOT A VALID OPERATION! Exactly because of
messes like this.
So no. No way am I pulling a big VFS tree that apparently has random
unknown aliased commits in other trees.
