Are "fixed in stone" kernel ABIs being created here?Are "fixed in stone" kernel ABIs being created here?Posted Mar 19, 2009 15:02 UTC (Thu) by sbishop (guest, #33061)Parent article: A look at ftrace
Reading this over makes me wonder if the userspace-visible ABIs exposed by these tracers are fixed in stone. Or are they intended to be only for kernel developers, users beware?
