b0f673c4626e4cb1db7785287eaeed2731dfefe8Bryan Cantrill# When we have dtrace_proc (but lack dtrace_kernel), we expect to be able to
b0f673c4626e4cb1db7785287eaeed2731dfefe8Bryan Cantrill# read certain curpsinfo/curlwpsinfo/curcpu fields even though they require
b0f673c4626e4cb1db7785287eaeed2731dfefe8Bryan Cantrill# reading in-kernel state. However, there are other fields in these translated
b0f673c4626e4cb1db7785287eaeed2731dfefe8Bryan Cantrill# structures that we know we shouldn't be able to read, as they require reading
b0f673c4626e4cb1db7785287eaeed2731dfefe8Bryan Cantrill# in-kernel state that we cannot read with only dtrace_proc. Finally, there
b0f673c4626e4cb1db7785287eaeed2731dfefe8Bryan Cantrill# are a few fields that we may or may not be able to read depending on the
