Ok, I do not have a system with a 2.5 kernel, but here are some results anyway: after 210.000 renames: 2.2.20 ext2 1535/s 2.4.20 ext2 3087/s !! ext3 1263/s !? - 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/
