We're seeing build failures on i386 and x86 with Clang:

More info to follow soon.
Caused by 3b8cc6298724 ("blk-cgroup: Optimize blkcg_rstat_flush()")
which is missing its prerequisite b5a9adcbd5dc ("blk-cgroup: Return
-ENOMEM directly in blkcg_css_alloc() error path"). With three Fixup:
patches following, it is one of those patches where I wonder if it
is worth the trouble.
