Jonathan Lemon fcd30ae066 bpf/xskmap: Return ERR_PTR for failure case instead of NULL. ... When kzalloc() failed, NULL was returned to the caller, which tested the pointer with IS_ERR(), which didn't match, so the pointer was used later, resulting in a NULL dereference. Return ERR_PTR(-ENOMEM) instead of NULL.
