Subject: linux-next: manual merge of the target-updates tree with the nfsd
tree
Hi Nicholas,
Today's linux-next merge of the target-updates tree got conflicts in:
drivers/infiniband/ulp/iser/iser_memory.c
drivers/infiniband/ulp/isert/ib_isert.c
between commit:
6c7b6d2d442c ("IB: merge struct ib_device_attr into struct ib_device")
from the nfsd tree and commits:
6d2cb3ad4bc2 ("iser-target: Support the remote invalidation exception")
9a4a71456262 ("IB/iser: Support the remote invalidation exception")
from the target-updates tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
