[PATCH 0/3] mm/vmalloc: fix size check and few cleanups

From: Roman Penyaev
Date: Thu Jan 03 2019 - 10:00:21 EST

The first patch in series fixes size check for remap_vmalloc_range_partial()
which can lead to kernel crash by unfaithful userspace mapping. Others two
are minor cleanups.

Roman Penyaev (3):
mm/vmalloc: fix size check for remap_vmalloc_range_partial()
mm/vmalloc: do not call kmemleak_free() on not yet accounted memory
mm/vmalloc: pass VM_USERMAP flags directly to __vmalloc_node_range()
