Hi all,

Today's linux-next merge of the mm-unstable tree got a conflict in:

  drivers/android/binder/page_range.rs

between commit:

  8ef2c15aeae07 ("rust_binder: check ownership before using vma")

from the char-misc.current tree and commit:

  3c9b6aa5c9119 ("mm: rename zap_page_range_single() to zap_vma_range()")

from the mm-unstable tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
