Dear Maintainer,
When running bcc on kernel newer than 6.19, it reports following error
(use execsnoop-bpfcc as an example):

Upstream issue: https://github.com/iovisor/bcc/issues/5501
Upstream commit to fix:
https://github.com/iovisor/bcc/commit/c3f35ecca18b1ce926bd272f60f6d4465656a80b
However, the upstream seems has not released a new version yet, so this
might be necessary to be included as a patch. This also affects users of
forky and trixie-backports.
