rcu: just rename call_rcu_bh instead of making it a macro
Seems that I found a box that has a config that passes call_rcu_bh as a function pointer (see net/sctp/sm_make_chunk.c), so declaring the call_rcu_bh has a macro function isn't good enough. This patch makes it just another name of call_rcu for rcupreempt. Signed-off-by: Steven Rostedt <srostedt@redhat.org> Reviewed-by: "Paul E.
