libfc: Replace rcu_assign_pointer() with RCU_INIT_POINTER()
The uses of "rcu_assign_pointer()" are NULLing out the pointers. According to RCU_INIT_POINTER()'s block comment: "1. This use of RCU_INIT_POINTER() is NULLing out the pointer" it is better to use it instead of rcu_assign_pointer() because it has a smaller overhead. The following Coccinelle semantic patch was used: @@ @@ - rcu_assign_pointer + RCU_INIT_POINTER (..., NULL) Signed-off-by: Andreea-Cristina Bernat <bernat.ada@gmail.com> Acked-by: Vasu Dev <vasu.dev@intel.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
