Message-Id: <20150210194804.288708936@linux.com> Date: Tue, 10 Feb 2015 13:48:04 -0600 From: Christoph Lameter <cl@...ux.com> To: akpm@...uxfoundation.org Cc: linux-mm@...ck.org, penberg@...nel.org, iamjoonsoo@....com, Jesper Dangaard Brouer <brouer@...hat.com> Subject: [PATCH 0/3] Slab allocator array operations V2 V1->V2: - Allocator will determine how to acquire the objects. Remove the flags that we exposed to the subsystems in V1. - Restructure patch a bit to minimize size - Add material provided by Jesper. Attached a series of 3 patches to implement functionality to allocate arrays of pointers to slab objects. This can be used by the slab allocators to offer more optimized allocation and free paths. Allocator performance issues were discovered by the network subsystem developers when trying to get the kernel to send at line rate to saturate a 40G link. Jesper developed special queueing methods to compensate for the performance issues.
