RDMA/siw: Fix DEFINE_PER_CPU compilation when ARCH_NEEDS_WEAK_PER_CPU
The initializer for the variable cannot be inside the macro (and zero initialization isn't needed anyhow). include/linux/percpu-defs.h:92:33: warning: '__pcpu_unique_use_cnt' initialized and declared 'extern' extern __PCPU_DUMMY_ATTRS char __pcpu_unique_##name; \ ^~~~~~~~~~~~~~ include/linux/percpu-defs.h:115:2: note: in expansion of macro 'DEFINE_PER_CPU_SECTION' DEFINE_PER_CPU_SECTION(type, name, "") ^~~~~~~~~~~~~~~~~~~~~~ drivers/infiniband/sw/siw/siw_main.c:129:8: note: in expansion of macro 'DEFINE_PER_CPU' static DEFINE_PER_CPU(atomic_t, use_cnt = ATOMIC_INIT(0)); ^~~~~~~~~~~~~~ Also the rules for PER_CPU require the variable names to be globally unique, so prefix them with siw_ Fixes: b9be6f18cf9e ("rdma/siw: transmit path") Fixes: bdcf26bf9b3a ("rdma/siw: network and RDMA core interface") Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
