Hm, with the local build test, I get the following error:

  CC [M]  sound/xen/xen_snd_front_shbuf.o
  In file included from sound/xen/xen_snd_front_shbuf.c:11:0:
  ./include/xen/xen.h:18:8: error: unknown type name ‘bool’
   extern bool xen_pvh;
           ^~~~

  ./arch/x86/include/asm/xen/interface.h:92:21: error: unknown type name

   DEFINE_GUEST_HANDLE(uint64_t);
                       ^
                        
Adding #include <linux/kernel.h> fixed the issue.

Did you really test your patches with the latest Linus tree?


thanks,

Takashi
