Subject: Re: linux-next: manual merge of the vfs tree with the v9fs tree
What's typically the right process for me to prep the merge for Linus?
Should I pull Al's patchset and then apply mine on top of it so I can
merge your merge fix or just have my for-linus tree based on his
current working merge (which I assume has Al's by now). Just a bit
confused because rebasing was discouraged last merge window -- but not
sure how to deal with the conflict without a rebase....
