The current implementation is not different from the original implementation. Jim had userspace return probes working on i386. BZ #2637 skipped probes on FC6 - Prasanna will investigate/work on the bug. BZ #2639 - Probe on "__kprobes" function ... it appears to be closed, Jim will follow up this up. Nofity pagefault patch - Anil proposed to backpor this patch to RHEL4U4. This patch sat on mm tree for a while without any objection, the chance it gets into the mainline is high. OLS paper - Gray Brian ?? withdrew his OLS paper (Instrumentation using systemtap) due to some concerns with the data that he got (kprobes related issues) systemtap portion ----------------- Attendees - All of the above and .. IBM - Vara Redhat - Martin, Will, David, Elena Intel - Josh, Thang RH summit: Frank will travel May 10/11/12. Summit itself May 30 through June 2. Kernel bug with page fault: BZ# 2637 see above Notify pagefault patch - see above roundtable Martin - worked on syscalls tapset tests. Will - added probes profiling in the translator to measure probe handlers performance (option -t) also update the man page. Skipped the detail discussion about presentation that he attended two week ago :-) David - talked about filtering stpd as a default mode. User space probes: See above. f2f: Several options 1. All day conference calls 2. Meet at OLS 3. Meet in UK in the falls.
