Hi all,
Today's linux-next merge of the kvm tree got a conflict in:
include/linux/mm.h
between commit:
4003f107fa2e ("mm: introduce FOLL_PCI_P2PDMA to gate getting PCI P2PDMA pages")
from the block tree and commit:
93c5c61d9e58 ("mm/gup: Add FOLL_INTERRUPTIBLE")
from the kvm tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
