Re: [PATCH] Check for NULL ptr of btf in codegen_asserts

Hello:

This patch was applied to bpf/bpf-next.git (master)
by Andrii Nakryiko [off-list ref]:

On Mon, 23 May 2022 15:49:17 -0400 you wrote:
bpf_object__btf() can return a NULL value.  If bpf_object__btf returns
null, do not progress through codegen_asserts(). This avoids a null ptr
dereference at the call btf__type_cnt() in the function find_type_for_map()
