I may be misunderstanding this, but looking at this portion of code from the oom task killer... Isn't it dangerous to give a process PF_MEMALLOC and then only pass it a SIGTERM? My take is that the high priority bump up should only happen for the force_sig(SIGKILL,p).
/* * We give our sacrificial lamb high priority and access to * all the memory it needs. That way it should be able to * exit() and clear out its resources quickly... */ p->counter = 5 * HZ; p->flags |= PF_MEMALLOC;
/* This process has hardware access, be more careful. */ if (cap_t(p->cap_effective) & CAP_TO_MASK(CAP_SYS_RAWIO)) { force_sig(SIGTERM, p); } else { force_sig(SIGKILL, p); }
