Do the (2) above mean that some platform's gcc is borked?
(I don't see these on i386 or x86_64.)

I can see that warning on 32-bit i386 (X86_32), but if I change the
"%lu" to "%u", it causes this warning on 64-bit x86_64:

fs/ecryptfs/miscdev.c:433:38: warning: format '%u' expects type 'unsigned int', but argument 4 has type 'long unsigned int'

so how is this supposed to be handled?

Thanks.
