Hi all,

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

fs/coredump.c: In function 'dump_user_range':
fs/coredump.c:923:40: warning: left-hand operand of comma expression has no effect [-Wunused-value]
  923 | #define dump_page_copy(src, dst) ((dst), (src))
      |                                        ^
fs/coredump.c:948:58: note: in expansion of macro 'dump_page_copy'
  948 |                         int stop = !dump_emit_page(cprm, dump_page_copy(page, dump_page));
      |                                                          ^~~~~~~~~~~~~~
