Subject: module-suspend-on-idle: Move vacuum code to core
X-Git-Tag: 1.0_branch~359
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3ebc8f8e88f1d0bff1a40f1097d472192fa7c02f;p=profile%2Fivi%2Fpulseaudio.git

module-suspend-on-idle: Move vacuum code to core

pa_core_maybe_vacuum now vacuums if there are either no streams or all devices are suspended.
The mempool_vacuum argument to module-suspend-on-idle is gone and defaults to true now.
