Yes. Layout of files in procfs should be treated as a part of ABI. IOW, you make incompatible change - things break. Folks, file in /proc is not different from a syscall in that respect - changing layout has the same effect as changes of layout in syscall arguments. IOW, don't do that. - 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/
