Note that it is not hard to support these in kgdb. I have gdb scripts that already provide equivalents to 'show lockchain' and many other commands. However, the problem with textdumps (which are still worth reporting), is that for hard bugs a developer often wants to ask the submitter for specific information, and won't know what to ask for until looking at the general information. There simply isn't a way to grab all the possible information up front in textdumps. -- John Baldwin _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
