#1671259 — linux-next: build warning after merge of the file-locks tree

Hi Jeff,

After merging the file-locks 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

  ee6b2b8e0a8f ("mm: drop "wait" parameter from write_one_page()")

Cheers,
Stephen Rothwell

This is fixed up by commit

in the akpm-current tree.
