This patchset introduces batched operations for the per-cpu variant of the array map.
It also introduces a standard way to define per-cpu values via the 'BPF_PERCPU_TYPE()' macro, which handles the alignment transparently. This was already implemented in the selftests and was merely refactored out to libbpf, with some simplifications for reuse.
The tests were updated to reflect all the new changes.
v1 -> v2: - Amended a more descriptive commit message
