[Qemu-devel] [PATCH v5 03/28] migration: remove use of qemu_bufopen from vmstate tests |
Date: |
Fri, 18 Mar 2016 14:30:38 +0000 |
Some of the test-vmstate.c test cases use a temporary file
while others use a memory buffer. To facilitate the future
removal of the qemu_bufopen() function, convert all the tests
to use a temporary file.
