Hi Andrew,

I think you modified the commit log before applying this patch.
I just noticed a typo.


commit 411865d8dd2c31f56eefc54bc16fabb47e1bfb73
Author: Masahiro Yamada <yamada.masahiro@socionext.com>
Date:   Wed Nov 6 16:07:08 2019 +1100

    arch: sembuf.h: make uapi asm/sembuf.h self-contained

    Uuserspace cannot compile <asm/sembuf.h> due to some missing type
    definitions.  For example, building it for x86 fails as follows:



If possible, could you fix up  s/Uuserspace/Userspace/  ?


Thanks.
Masahiro Yamada
