RDMA/srpt: Fix RCU debug build error
Combination of CONFIG_DEBUG_OBJECTS_RCU_HEAD=y and CONFIG_INFINIBAND_SRPT=m produces the following build error. ERROR: "init_rcu_head" [drivers/infiniband/ulp/srpt/ib_srpt.ko] undefined! make[1]: *** [scripts/Makefile.modpost:92: __modpost] Error 1 make: *** [Makefile:1216: modules] Error 2 The reason to it that init_rcu_head() is not exported and not supposed to be used in modules. It is needed for dynamic initialization of statically allocated rcu_head structures. Fixes: 795bc112cd5a ("IB/srpt: Make it safe to use RCU for srpt_device.rch_list") Fixes: a11253142e6d ("IB/srpt: Rework multi-channel support") Signed-off-by: Bart Van Assche <bart.vanassche@wdc.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
