…d in the source Two pre-existing defects of an example were reported and left for the maintainer to decide on, who answered that defects are always fixed; and a question about which CPU a hook runs on was answered by measuring instead of by reading NF_HOOK's callers and the receive path.

…it before pushing A kernel thread left by a test pinned the core, so reload kept the old one and an A/B answered for code that was never loaded; srcversion says whether the running core is the built one. In the same round, debug instrumentation committed by accident reached a pull request, because only the working tree had been read. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Four lessons from the percpu round. Two pre-existing defects of an example were reported and left for the maintainer to decide on; a question about which CPU a hook runs on was answered by measuring rather than by reading the kernel source; a kernel thread left behind by a test pinned the core, so a reload kept the old one and an A/B answered for code that was never loaded; and debug instrumentation committed by accident reached a pull request.
AGENTS.mdsays a defect found on the way is fixed, that kernel behaviour is read in the source, how to tell whether the running core is the one just built, and that the commit itself is read before pushing.
