This reduces sizeof(struct scan_control):

Allow INFINIBAND without INFINIBAND_ADDR_TRANS because fuzzing has been
finding fair number of CM bugs. So provide option to disable it.

CIFS_SMB_DIRECT code depends on INFINIBAND_ADDR_TRANS provided symbols.
So declare the kconfig dependency. This is necessary to allow for

The new memory.min limit is similar to memory.low, just no bypassing it
when reclaim is desparate. Prefer oom kills before reclaim memory below
memory.min. Sharing more code with memory_cgroup_low() is possible, but
the idea is posted here for simplicity.

When targeting reclaim to a memcg, protect that memcg from reclaim is
memory consumption of any level is below respective memory.low.
