Hi Avantika,

I haven't had a chance to work on them unfortunately, I've been pretty
tied up with other work.

I've rebased the subset of patches necessary to get the raw syscall
tracepoints working and to ensure that none of the unworking ftrace
syscall events show up. This won't give you the per syscall events that
ftrace can provide, but if all you need is the raw tracepoints they will
work. I'll send them to the mailing list shortly.


Jason: It seems that publishing a tree for you to work on will be time
consuming due to legal concerns of publishing the whole kernel tree.
Rather than go down that path it will be easier for me to just send you
the patches directly. I'll try to find some time to rebase them and send
them to you before I go away next week.


Cheers,
-Ian
