Hi,
since late June I receive several mails per day about this commit but
they are all false-positive.
Commit 670d0a4b10704667765f7d18f7592993d02783aa can't introduce *new*
warnings, it only change how address-spaces are displayed in sparse's
warnings (for example, the address space for __user pointers were
displayd as '<asn:1>', now it's nicely displayed as '__user', same
for '__iomem', '__percpu' and '__rcu').
Isn't it possible to ignore some commits like this one?
Or, even better, should it be possible to only report when a new
warning is effectively added, not when its content is simply modified?
If not it would be nice to be able to see the difference in a diff-like
format.
Best regards,
-- Luc

Hi Luc,
Sorry for the inconvenience, we'll ignore this commit firstly.

Thanks for your advice, we'll seriously consider it.
