Does anyone besides me notice that the more Dave and I argue the longer and longer the list of extenuating circumstances gets in order for Dave to continue to be right? In this email, I'm not right if the data is on separate partitions. Dave, do you realize how many people, despite advice to the contrary, put everything on one honk'in / partition? For all those people, I'm right. Dave, you're confusing the rule with the exceptions to the rule. I'm right as a general rule, and you're pointing out all the exceptions to the rule to try to prove that I'm wrong. > Actually, it can even be threaded to the point where > block allocations on the same filesystem can occur in > parallel as long as it is being done for different > block groups. Prove it. If you can code multi-threading SMP block and inode allocation using a non-preemptive kernel (which Linux is) ON THE SAME PARTITION, I will eat my hard drive. - 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/
