I think the problem is that I haven't allocated system call numbers for any arches other than x86 - even the x86 syscall numbers are provisional until the patchset is taken upstream. I'm not sure of the best way to deal with this - make the samples dependent on the X86 arch? > > samples/vfs/test-fsinfo.c:180:30: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 2 has type '__u64' {aka 'long unsigned int'} [-Wformat=] > > printf("\tmax file size: %llx\n", f->max_file_size); Sigh. On powerpc __u64 is unsigned long, but on x86_64 it's unsigned long long. Is it possible to shift all arches to use unsigned long long for __u64? David
