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

    It is just a matter of missing include directive.
    
    Include <linux/posix_types.h> to make it self-contained, and add it to
    the compile-test coverage.
