From: Daniel Borkmann Date: Fri, 13 May 2016 17:08:29 +0000 (+0200) Subject: bpf, x86/arm64: remove useless checks on prog X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=93a73d442d370e20ed1009cd79cb29c4d7c0ee86;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git bpf, x86/arm64: remove useless checks on prog There is never such a situation, where bpf_int_jit_compile() is called with either prog as NULL or len as 0, so the tests are unnecessary and confusing as people would just copy them. s390 doesn't have them, so no change is needed there.
