Currently I > don't know any problem with it. I have a problem... in recent host kernels, isn't SINGLESTEP also trapping for syscall instructions? Also, you say that SINGLESTEP_SYSEMU does automatic syscall overwriting with -1 or emulates that - I suspect it being in the reorganize patches, but you don't mention it in the changelogs here, only about the UML patches. So, I'd personally accept only the -reorganize ones and hold on the rest - which is probably achieved with mainline SINGLESTEP fixes in 2.6.9 (or which could be discussed). Sorry for being so late (I'd say "Call me a lamer" :-) ) in discussing this, but I hadn't the time to study patches and realize this. > Bodo -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
