From: Pavel Emelyanov Date: Thu, 13 Jan 2011 01:00:46 +0000 (-0800) Subject: user_ns: improve the user_ns on-the-slab packaging X-Git-Tag: v2.6.38-rc1~298 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6164281ab7a4d3bd42588d6b25984e960a2e032f;p=pandora-kernel.git user_ns: improve the user_ns on-the-slab packaging Currently on 64-bit arch the user_namespace is 2096 and when being kmalloc-ed it resides on a 4k slab wasting 2003 bytes. If we allocate a separate cache for it and reduce the hash size from 128 to 64 chains the packaging becomes *much* better - the struct is 1072 bytes and the hole between is 98 bytes.
