From 6d7e73d62fa32813b6f6a3575db2e9b5e0d43387 Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Thu, 15 May 2014 19:22:06 +0800 Subject: virtio-blk: Allow config-wce in dataplane Dataplane now uses block layer. Protect bdrv_set_enable_write_cache with aio_context_acquire and aio_context_release, so we can enable config-wce to allow guest to modify the write cache online.
