Ah. I realy hoped that cap_task_kill() was already killed. And I googled this patch: http://marc.info/?l=linux-kernel&m=120422062515386
But I checked 2.6.25-rc5-mm1.bz2, it is still here. And I didn't find anything related in http://userweb.kernel.org/~akpm/mmotm/. I even checked http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=history;f=security/commoncap.c
So, is it still here or killed? If it is dead - great ;)
Oleg.
