tracing: Clean up hist_field_flags enum (0d7a8325) · Commits · 戴 / test

As we add more flags, specifying explicit integers for the flag values becomes more unwieldy and error-prone - switch them over to left-shift values. Link: http://lkml.kernel.org/r/e644e4fb7665aec015f4a2d84a2f990d3dd5b8a1.1506105045.git.tom.zanussi@linux.intel.com Signed-off-by:
