this macro is pretty gross. these are the problems i see: - assumes 'int error' - assumes 'struct lwp *l = curlwp' - assumes 'name' is something - assumes 'ns' is something - returns from macro all of those should be resolved. 4 are simple, they can be easy inputs. the return issue is more difficult, and perhaps should be revisited (ie, perhaps just skip over this entry instead of assuming return is right.) > Since the XSTATE block uses the same format on i386 and amd64, the code > does not have to conditionalize between 32-bit and 64-bit ELF format > on that.
