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") -- Cheers, Stephen Rothwell
