[Crash-utility] display function parameters for call stack

Hi Dave, I notice there was some discussion around on enabling the display function parameters feature for crash tool. Like this one: http://www.redhat.com/archives/crash-utility/2009-May/msg00016.html Although the answer seems to be quite clear, it should be hard to support such feature. But does this feature cannot be done anyway? I think this feature would be great in assisting kernel debug. The main feature I require, first should be know each param's value in the call stack. Then it is better to know each call stack's param's name. Like for do_vfs_ioctl function, it is better to display as: do_vfs_ioctl(filp=xxx, fd=xxx, cmd=xxx, arg=xxx) Do you have any idea on how this could be implemented? Thanks, Lei
