https://git.0xinfinity.dev/distro/kernel.git/atom?h=master2024-11-11T16:18:39Zselftests/bpf: Test the update operations for htab of maps2024-11-11T16:18:39ZHou Tao2024-11-06T06:35:42Zurn:sha1:cb55657c7fc800b722f2ef0afaf4d9c3c8902e6d
Add test cases to verify the following four update operations on htab of
maps don't trigger lockdep warning:
(1) add then delete
(2) add, overwrite, then delete
(3) add, then lookup_and_delete
(4) add two elements, then lookup_and_delete_batch
Test cases are added for pre-allocated and non-preallocated htab of maps
respectively.
