Re: [PATCH net-next v2] selftests: net: exit cleanly on SIGTERM / timeout

Jakub Kicinski wrote:

ksft runner sends 2 SIGTERMs in a row if a test runs out of time. Handle this in a similar way we handle SIGINT - cleanup and stop running further tests.

Because we get 2 signals we need a bit of logic to ignore the subsequent one, they come immediately one after the other (due to commit 9616cb34b08e ("kselftest/runner.sh: Propagate SIGTERM to runner child")).

This change makes sure we run cleanup (scheduled defer()s) and also print a stack trace on SIGTERM, which doesn't happen by default. Tests occasionally hang in NIPA and it's impossible to tell what they are waiting from or doing.
