Since I do not seem to be able to find any review comments regarding the variable naming in the v1's thread, let's ask stakeholders. Are folks involved in the trace2 subsystem (especially Jeff Hostetler---already CC:ed---who presumably has the most stake in it) OK with the naming convention of the multi-word variable? This is the first use of multi-word variable name in tr2_ctr, and thus will establish whatever convention you guys want to use. I do have a slight preference of "writeout-only" over "writeout_only" but that is purely from visual appearance. If there is a desire to keep the names literally reusable as identifiers in some languages used to postprocess trace output, or something, that might weigh differently. > t/t5351-unpack-large-objects.sh | 6 +++--- > trace2.c | 1 - > trace2.h | 4 ++++ > trace2/tr2_ctr.c | 10 ++++++++++ > wrapper.c | 19 ++----------------- > wrapper.h | 5 ----- > 6 files changed, 19 insertions(+), 26 deletions(-) Very nice to see clean-up patch that reduces the amount of code. Nicely done. Thanks, will queue. If folks do not find issues in a few days, let's merge it to 'next'.
