[Xen-changelog] Max xen skbuff allocation is now 64KB. kmem caches only
# HG changeset patch
# User kaf24@xxxxxxxxxxxxxxxxxxxx
# Node ID cc1c250e672d138b355444881c9c907824e1f336
# Parent b5c95258fe59e0a7f4301c6607775b511c985a30
Max xen skbuff allocation is now 64KB. kmem caches only
get populated with objects on first allocation, so if large
caches end up being unused, they don't actually cost us
very much.
