From: Chandan Somani Date: Fri, 3 Oct 2025 21:59:26 +0000 (-0700) Subject: block: enable stats-intervals for storage devices X-Git-Tag: v10.2.0-rc1~38^2~10 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9f0c763e16c65d3aab5f3f17768df58321874685;p=thirdparty%2Fqemu.git block: enable stats-intervals for storage devices This patch allows stats-intervals to be used for storage devices with the -device option. It accepts a list of interval lengths in JSON format. It configures and collects the stats in the BlockBackend layer through the storage device that consumes the BlockBackend.
