Subject: [GIT PULL] KUnit next update for Linux 6.8-rc1
Hi Linus,
Please pull the following KUnit next update for Linux 6.8-rc1.
This KUnit update for Linux 6.8-rc1 consists of:
- a new feature that adds APIs for managing devices introducing
a set of helper functions which allow devices (internally a
struct kunit_device) to be created and managed by KUnit.
These devices will be automatically unregistered on
test exit. These helpers can either use a user-provided
struct device_driver, or have one automatically created and
managed by KUnit. In both cases, the device lives on a new
kunit_bus.
- changes to switch drm/tests to use kunit devices
- several fixes and enhancements to attribute feature
- changes to reorganize deferred action function introducing
KUNIT_DEFINE_ACTION_WRAPPER
- new feature adds ability to run tests after boot using debugfs
- fixes and enhancements to string-stream-test:
- parse ERR_PTR in string_stream_destroy()
- unchecked dereference in bug fix in debugfs_print_results()
- handling errors from alloc_string_stream()
- NULL-dereference bug fix in kunit_init_suite()
diff is attached.
thanks,
-- Shuah
