The warning described on patch "tracing: Increase PERF_MAX_TRACE_SIZE to handle Sentinel1 and docker together" can be triggered with a perf probe on do_execve with a large path. As PATH_MAX is larger than PERF_MAX_TRACE_SIZE (2048 before the patch), the warning will trigger.

The fix was included in 5.16, so backporting to 5.15 and earlier LTS kernels. Also included is a patch that better describes the attempted allocation size.

All now queued up, thanks.
