A small query.
How do I look at the tree where the build is failing.

Subject: linux-next: build failure after merge of the akpm tree
After merging the akpm tree, today's linux-next build (x86_64
allmodconfig) failed like this:
ERROR: modpost: "cgroup_get_e_css" [drivers/nvme/host/nvme-fc.ko]
ERROR: modpost: "cgroup_get_e_css" [drivers/block/loop.ko] undefined!
Caused by patch
kernel/cgroup/cgroup.c: don't export cgroup_get_e_css twice
I am not sure what happened here, but this patch interacts with commit
6b658c4863c1 ("scsi: cgroup: Add cgroup_get_from_id()")
from the scsi-mkp tree which adds the EXPORT_SYMBOL_GPL().
I have reverted that akpm tree patch for today.
