linux-next: build warning after merge of the akpm-current tree

[Stephen Rothwell]

Hi Andrew,

After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

fs/jfs/jfs_metapage.c: In function 'force_metapage':
fs/jfs/jfs_metapage.c:714:2: warning: ignoring return value of 'write_one_page', declared with attribute warn_unused_result [-Wunused-result]
  write_one_page(page);
  ^
fs/jfs/jfs_metapage.c: In function 'release_metapage':
fs/jfs/jfs_metapage.c:759:4: warning: ignoring return value of 'write_one_page', declared with attribute warn_unused_result [-Wunused-result]
    write_one_page(page);
    ^

Introduced by commit

  f8652aebee02 ("mm: drop "wait" parameter from write_one_page()")

These call sites were updated for the droppping of the argument, but
not for the addition of __must_check :-(
