Subject: [PATCH bpf-next v2 0/5] cleanup for data casting
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.
[0] https://lore.kernel.org/bpf/a31efed5-a436-49c9-4126-902303df9766@iogearbox.net/
v2:
- update subject and commit msg of patch 5.
- attach ack of Yonghong.
v1: https://lore.kernel.org/bpf/20220716125108.1011206-1-pulehui@huawei.com/
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: Change the casting about jited_ksyms and jited_linfo
