From 10817bf09d5f8cb22711fb0ee8d8da49f6f05f89 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Tue, 1 Sep 2015 14:48:02 +0100 Subject: coroutine: move into libqemuutil.a library The coroutine files are currently referenced by the block-obj-y variable. The coroutine functionality though is already used by more than just the block code. eg migration code uses coroutine yield. In the future the I/O channel code will also use the coroutine yield functionality. Since the coroutine code is nicely self-contained it can be easily built as part of the libqemuutil.a library, making it widely available. The headers are also moved into include/qemu, instead of the include/block directory, since they are now part of the util codebase, and the impl was never in the block/ directory either.
