I've never seen valgrind actually working against UML - Jeff Dike did some work on Valgrind on this area time ago, but it wasn't merged and the Valgrind author said that Valgrind does not at all supports program using the "clone" call. And UML is one heavy user of this call.

Time is limited - managing two trees (in this case, two 2.4 trees) and porting patches back and forth between them is a hard, difficult, error-prone work. However, I've not claimed "abandoning" the 2.4 tree. However, who uses the 2.4 tree wants stability over everything else (in most cases), otherwise would use the 2.6 tree. So, actually, we cannot debug invasive patches on 2.4: you need lots of users testing and reporting about them and helping to narrow down possible bugs. So, for instance, it would be useless to backport the /proc/sysemu feature (which was a bit tricky to get right on 2.6 already, especially because uncovered some bugs in the SYSEMU host patch). > Blaisorblade wrote: > >Jeff, I've seen the beginning of your work on back-porting all the patches > >from 2.6 to 2.4... > >It's a huge work, but what is more important, it could obviously hurt > >stability... > >So, I'd suggest to follow this policy to choose the work to merge: > >- reduce *a lot* what is going to be merged... no new features, no code > >cleanups (especially NOT the Makefiles cleanups)... > >- concentrate on stability... and on backing out the hostfs rewrite. -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
