Subject: Re: linux-next: build failure after merge of the akpm-current tree
Hi Stephen,
Thanks for your report and the fix for it. The 0-day project has reported several days ago,
but this patch set is still in discussion, so I am waiting for more days to see if other
developers
have any other questions.
I am confused that how to deal with your patch if I need to work out the V2 patch set. Perhaps,
pick up your fix and add your efforts in the change log?
Thanks,
Eric
