The fix up looks correct to me.

Of the 7 patches in my series [1], the first two are in mm, and provide
some prerequisites. The remaining patches apply to block, bio, fs, and
iov_iter, and that's where this merge conflict happened.
Also, there's still some upcoming churn (more patchset revisions are
coming), as reviews are still active and this one isn't perfected yet.
So I see two obvious solutions. Either:
a) Only do the first two patches for now, and leave them in Andrew's
tree. After the next release, do the remaining 5 patches via the block
tree, or
b) Move the whole series to the block tree now, or
c) something else?
Andrew, Jens, any preference here?
