Hi Andrew, I think this patch has already been picked up to your tree, but I noticed a typo in the commit message just now. Please see below. On Wed, Oct 30, 2019 at 3:40 PM Masahiro Yamada [off-list ref] wrote:
The user-space cannot compile <asm/ipcbuf.h> due to some missing type

It is just a matter of missing include directive.
Include <asm/posix_types.h> to make it self-contained, and add it toInclude <linux/posix_type.h> to make ... Could you please fix it up locally? Thank you. Masahiro Yamada
