xen/tmem: Don't use self[ballooning|shrinking] if frontswap is off.

2013-05-15T14:27:50+00:00

There is no point. We would just squeeze the guest to put more and
more pages in the swap disk without any purpose.

The only time it makes sense to use the selfballooning and shrinking
is when frontswap is being utilized.

xen/tmem: Remove the usage of '[no|]selfballoon' and use 'tmem.selfballooning' bool instead.

2013-05-15T14:27:49+00:00

As the 'tmem' driver is the one that actually sets whether
it will use it (or not) so might as well make tmem responsible
for this knob.

xen/tmem: Remove the boot options and fold them in the tmem.X parameters.

2013-05-15T14:27:47+00:00

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.

xen/tmem: s/disable_// and change the logic.

2013-05-15T14:27:46+00:00

The variety of disable_[cleancache|frontswap|selfshrinking] are
making this a bit complex. Just remove the "disable_" part and
change the logic around for the "nofrontswap" and "nocleancache"
parameters.

xen/tmem: Fix compile warning.

2013-05-15T14:27:45+00:00

We keep on getting:
drivers/xen/tmem.c:65:13: warning: ‘disable_frontswap_selfshrinking’ defined but not used [-Wunused-variable]

if CONFIG_FRONTSWAP=y and # CONFIG_CLEANCACHE is not set

xen/tmem: Split out the different module/boot options.

2013-05-15T14:27:44+00:00

There are three options - depending on what combination of
CONFIG_FRONTSWAP, CONFIG_CLEANCACHE and CONFIG_XEN_SELFBALLOONING
is used. Lets split them out nicely out in three groups to
make it easier to clean up.
