[Devel] [PATCH rh7] tcache/tswap: enable by default

[Vladimir Davydov]

These subsystems has proven to be stable, so let's enable them by
default. If anything goes wrong, they can always be disabled by writing
'N' to /sys/module/{tcache,tswap}/parameters/active.

Currently tcache/tswap are enabled by vcmmd, but I want to drop this
code from there.
