From: Wang Hai <wanghai38@huawei.com> stable inclusion from linux-4.19.198 commit b86fdd413e4296e1e3b282b405e32d2da8f1ea23 -------------------------------- [ Upstream commit 7c6090ee2a7b3315410cfc83a94c3eb057407b25 ] Fix to return a negative error code from the error handling case instead of 0, as done elsewhere in this function. If bpf_map_update_elem() failed, main() should return a negative error.
