commit: 73ce4317bf983282593aff710b112a7e705620c3 [1267/1290] RDS: make sure we
post recv buffers
reproduce:
# apt-get install sparse

make ARCH=x86_64 allmodconfig

sparse warnings: (new ones prefixed by >>)
>> net/rds/ib_recv.c:382:28: sparse: incorrect type in initializer (different
>> base types)
net/rds/ib_recv.c:382:28: expected int [signed] can_wait
net/rds/ib_recv.c:382:28: got restricted gfp_t
net/rds/ib_recv.c:828:23: sparse: cast to restricted __le64
