SubjectRe: [PATCH 3/3] arch: sembuf.h: make uapi asm/sembuf.h self-contained
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
