[Vserver] kprobes
hi, i saw this on lwn.net: IBM developerWorks [0] shows how to use Kprobes to debug the Linux kernel. "The benefits of using Kprobes are many. printk's can be inserted without rebuilding and rebooting the kernel. Processor registers can be logged and even modified for debugging -- without disruption to the system. Similarly, Linux kernel data structures can also be logged and even modified non-disruptively as well. You can even debug race conditions on SMP systems with Kprobes -- and save yourself the trouble of all that rebuilding and rebooting. You'll find kernel debugging is faster and easier than ever." maybe that could be _real_ useful for the vserver project ? :-) [0]: http://www-106.ibm.com/developerworks/library/l-kprobes.html?ca=dgr-lnxw04Kprobe -- regards, Georges Toth ___ Vserver mailing list [EMAIL PROTECTED] http://list.linux-vserver.org/mailman/listinfo/vserver
