Swap space limits Linux 2.4.10 and later, and Linux 2.5 support any combination of swap files or swap devices to a maximum number of 32 of them. Prior to Linux 2.4.10, the limit was any combination of 8 swap files or swap devices. On x86 architecture systems, each of these swap areas has a limit of 2 GiB. ~Randy - 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/
