All those are already merged, after long reviewing phases and lots of testing, right? I think the next step for people working in this area, in preparation for this BoF, is to list what are their current efforts, like Ian et all did in: https://linuxplumbersconf.org/event/4/contributions/291/ - Arnaldo > Best regards, > Alexey > > [1] https://marc.info/?l=linux-kernel&m=154149439404555&w=2 > [2] https://marc.info/?l=linux-kernel&m=154817912621465&w=2 > [3] https://marc.info/?l=linux-kernel&m=155293062518459&w=2 > [4] https://www.kernel.org/doc/html/latest/admin-guide/perf-security.html -- - Arnaldo
