Current method of checking pointer error is not user friendly.
Especially the __must_check define makes this less intuitive.
Since, libbpf has an API libbpf_get_error() which checks pointer error,

Namely do a sk storage lookup then depending on data here decide if
we need to do more work or alternatively allow packet to PASS. Then
if we need to do more work consult task_struct for more information

This series adds helpers for sk_msg program type and based on feedback
from v1 adds *_task_* helpers and probe_* helpers to all networking
programs with perfmon_capable() capabilities.
The list of helpers breaks down as follows,

Device driver firmware can crash, and sometimes, this can leave your
system in a state which makes the device or subsystem completely
useless. Detecting this by inspecting /proc/sys/kernel/tainted instead
of scraping some magical words from the kernel log, which is driver
specific, is much easier.
