From 9caa6f3dbe20f2c506df6698386fce941fc6238a Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 5 Jun 2017 14:39:07 +0200 Subject: [PATCH] block: split BlockAcctStats creation and setup block_acct_destroy is called unconditionally in blk_delete, but there is no BlockAcctStats function that is called unconditionally in blk_new. Split block_acct_init in two, so that it will be possible to create a QemuMutex in block_acct_init and destroy it in block_acct_cleanup.
