[src/trunk]: src/sys remove checks for failure after memory allocation calls ...
details: https://anonhg.NetBSD.org/src/rev/e951dfbf3846
branches: trunk
changeset: 824315:e951dfbf3846
user: chs <chs%NetBSD.org@localhost>
date: Thu Jun 01 02:45:05 2017 +0000
description:
remove checks for failure after memory allocation calls that cannot fail:
kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()
all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.
