There is one in the next patch, of course. But with that patch you also get cpu_possible():
for (i = 0; i < NR_CPUS; i++) { if (!cpu_possible(i)) { ntfs_compression_buffers[i] = NULL; continue; }
Hope that clarifies, Rusty. -- Anyone who quotes me in their sig is an idiot. -- Rusty Russell. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
