# clatd calls mmap(MAP_LOCKED) with a 1M buffer. MAP_LOCKED first checks
# capable(CAP_IPC_LOCK), and then checks to see the requested amount is
# under RLIMIT_MEMLOCK. If the latter check succeeds clatd won't have
# needed CAP_IPC_LOCK. But this is not guaranteed to succeed on all devices
# so we permit any requests we see from clatd asking for this capability.
# See https://android-review.googlesource.com/127940 and
