That is strange. The patch removes a duplicate declaration of resched_cpu (on lines 768, 954) of the file kernel/rcu/tree.c of the latest git. The patch compiles fine here with the latest tip of the git tree. CC kernel/rcu/tree.o Can you please check if your tree.c has two declarations for resched_cpu? -- Pranith -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
