[PATCH bpf-next v3 0/2] bpf: add bpf_dynptr_memset() kfunc

[Ihor Solodrai <isolodrai@xxxxxxxx>]

Implement bpf_dynptr_memset() kfunc and add tests for it.

v2->v3:
  * nits and slow-path loop rewrite (Andrii)
  * simplify xdp chunks test (Mykyta) 
v1->v2:
  * handle non-linear buffers with bpf_dynptr_write()
  * change function signature to include offset arg
  * add more test cases

v2: https://lore.kernel.org/bpf/20250624205240.1311453-1-isolodrai@xxxxxxxx/
v1: https://lore.kernel.org/bpf/20250618223310.3684760-1-isolodrai@xxxxxxxx/
