[bpf-next,0/5] cleanup for data casting

Message

Pu Lehui July 16, 2022, 12:51 p.m. UTC

Previously, we found that memory address casting in libbpf
was not appropriate [0]. Memory addresses are conceptually
unsigned, (unsigned long) casting makes more sense. With the
suggestion of Daniel, we applied this cleanup to the entire
bpf, and there is no functional change.

Pu Lehui (5):
  bpf: Unify memory address casting operation style
  libbpf: Unify memory address casting operation style
  selftests: bpf: Unify memory address casting operation style
  samples: bpf: Unify memory address casting operation style
  selftests/bpf: Remove the casting about jited_ksyms and jited_linfo
