[Qemu-devel] [PATCH V6 1/7] memory, exec: Expose all memory block related flags. |
Date: |
Fri, 1 Jun 2018 16:10:23 +0800 |
From: Junyan He <address@hidden>
We need to use these flags in other files rather than just in exec.c,
For example, RAM_SHARED should be used when create a ram block from file.
We expose them the exec/memory.h
