Subject: [PATCH v3 0/3] restructure memfd code

This is a replacement for "Patch series restructure memfd code, v2"
which is currently in mmotm and consists of:
- mm: hugetlbfs: move HUGETLBFS_I outside #ifdef CONFIG_HUGETLBFS
- mm: memfd: split out memfd for use by multiple filesystems
- mm: memfd: remove memfd code from shmem files and use new memfd files

The above series incorrectly moves the memfd code out of shemm.c as
a separate commit.  Please let me know if there are any issues with
the way code is restructured/moved in this series.  Specifically,
the last patch.

While redoing the series, all sparse warnings in mm/shmem.c are fixed
in patch 1.  Patch 2 updates comments and file checking such that patch
3 is only code movement.

Mike Kravetz (3):
  mm/shmem: add __rcu annotations and properly deref radix entry
  mm/shmem: update file sealing comments and file checking
  mm: restructure memfd code
