Hi Jeff,

After merging the file-locks tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

mm/page-writeback.c: In function 'write_one_page':
mm/page-writeback.c:2380:15: warning: unused variable 'ret2' [-Wunused-variable]
int ret = 0, ret2;

Introduced by commit

4118ba44fa2c ("mm: clean up error handling in write_one_page")
