Subject: linux-next: build failure after merge of the fs-next tree

Hi all,

After merging the fs-next tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

/tmp/next/build/fs/ntfs/file.c: In function 'ntfs_file_mmap_prepare':
/tmp/next/build/fs/ntfs/file.c:657:13: error: implicit declaration of function 'vma_desc_test_flags'; did you mean 'vma_desc_set_flags'? [-Wimplicit-function-declaration]
  657 |         if (vma_desc_test_flags(desc, VMA_WRITE_BIT)) {
      |             ^~~~~~~~~~~~~~~~~~~
      |             vma_desc_set_flags

Caused by an interaction with commit:

  2c3b5ea7028fa (mm: reintroduce vma_desc_test() as a singular flag test)

from one of the mm trees, I've fixed it up as below and can carry as
needed.
