New topic branch for block + gup work?

[John Hubbard <jhubbard@xxxxxxxxxx>]

Hi Jens,

After you suggested a topic branch [1] as a way to address the recent
bio_map_user_iov() conflict in linux-next, I've reviewed a few more
patchsets in mm, and am now starting to suspect that a topic branch
would be ideal here.

Logan's "Userspace P2PDMA with O_DIRECT NVMe devices" series [2], my
"convert most filesystems to pin_user_pages_fast()" series [3], and the
block layer change from [1], all conflict in iov_iter*, and in
bio_map_user_iov().

Less of an issue but still worth considering, Dan's "Fix the DAX-gup
mistake" series [4] conflicts in gup.c, too.

Maybe:

    gup_bio

, or something like that, as a topic branch?

Everyone: thoughts, preferences here?
