tools/virtio: fix build caused by virtio_ring changes

2023-04-21T07:02:35+00:00

Fix the build dependency for virtio_test. The virtio_ring that is used from
the test requires container_of_const(). Change to use container_of.h kernel
header directly and adapt related codes.

tools/virtio: add krealloc_array

2020-12-18T21:14:30+00:00

krealloc_array is used in drivers/vhost/vringh.c, add it to avoid build
failure.

Drop WARN_ON_ONCE, because duplicated with the one in bug.h

compiler: Remove uninitialized_var() macro

2020-07-16T19:35:31+00:00

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

As recommended[2] by[3] Linus[4], remove the macro. With the recent
change to disable -Wmaybe-uninitialized in v5.7 in commit 78a5255ffb6a
("Stop the ad-hoc games with -Wno-maybe-initialized"), this is likely
the best time to make this treewide change.

tools/virtio: Use tools/include/list.h instead of stubs

2020-06-22T16:34:22+00:00

It should not make any significant difference but reduce stub code.
