20# clatd calls mmap(MAP_LOCKED) with a 1M buffer. MAP_LOCKED first checks
21# capable(CAP_IPC_LOCK), and then checks to see the requested amount is
22# under RLIMIT_MEMLOCK. If the latter check succeeds clatd won't have
23# needed CAP_IPC_LOCK. But this is not guaranteed to succeed on all devices
24# so we permit any requests we see from clatd asking for this capability.
