From 2ca62b044457e3aacaa06684974b0ff40b2f5a94 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Wed, 8 May 2013 17:12:44 -0400 Subject: xen/tmem: Remove the boot options and fold them in the tmem.X parameters. If tmem is built-in or a module, the user has the option on the command line to influence it by doing: tmem. instead of having a variety of "nocleancache", and "nofrontswap". The others: "noselfballooning" and "selfballooning"; and "noselfshrink" are in a different driver xen-selfballoon.c and the patches: xen/tmem: Remove the usage of 'noselfshrink' and use 'tmem.selfshrink' bool instead. xen/tmem: Remove the usage of 'noselfballoon','selfballoon' and use 'tmem.selfballon' bool instead. remove them. Also add documentation.
