Re: [PATCH v2] btrfs: reject root items with drop_progress and zero drop_level

[ZhengYuan Huang]

Thanks a lot for the explanation. I think I now understand the
intended use of the
Fixes: tag.

I still have one question, though. In this case, scripts/checkpatch.pl
warns that a
Fixes: tag should be added, which seems inconsistent with the submission
guidelines you pointed me to.

My understanding had been that patches should generally be sent only
after passing
checkpatch.pl cleanly, so I wanted to ask: is this kind of warning acceptable in
practice, or does it mean my local checkpatch.pl is outdated? If it is outdated,
should I generally use the latest checkpatch.pl when checking patches
before submission?

Thanks again,
ZhengYuan Huang
