Subject: [PATCH 0/6] Add kmalloc_array_node() and kcalloc_node()
Date: Wed, 27 Sep 2017 10:20:32 +0200	[thread overview]
Message-ID: <20170927082038.3782-1-jthumshirn@suse.de> (raw)

Our current memeory allocation routines suffer form an API imbalance,
for one we have kmalloc_array() and kcalloc() which check for
overflows in size multiplication and we have kmalloc_node() and
kzalloc_node() which allow for memory allocation on a certain NUMA
node but don't check for eventual overflows.

Johannes Thumshirn (6):
  mm: add kmalloc_array_node and kcalloc_node
  block: use kmalloc_array_node
  IB/qib: use kmalloc_array_node
  IB/rdmavt: use kmalloc_array_node
  mm, mempool: use kmalloc_array_node
  rds: ib: use kmalloc_array_node
