From 72ed076abf54cce939f706d673416f954ea47bcd Mon Sep 17 00:00:00 2001 From: Kumar Kartikeya Dwivedi Date: Sat, 1 Mar 2025 07:18:46 -0800 Subject: selftests/bpf: Add tests for extending sleepable global subprogs Add tests for freplace behavior with the combination of sleepable and non-sleepable global subprogs. The changes_pkt_data selftest did all the hardwork, so simply rename it and include new support for more summarization tests for might_sleep bit.
