From c0c2c0dad6a06e0c05e9a52d65f932bd54364c97 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 17 Jun 2021 20:57:19 +0200 Subject: lockdep/selftests: Fix selftests vs PROVE_RAW_LOCK_NESTING When PROVE_RAW_LOCK_NESTING=y many of the selftests FAILED because HARDIRQ context is out-of-bounds for spinlocks. Instead make the default hardware context the threaded hardirq context, which preserves the old locking rules. The wait-type specific locking selftests will have a non-threaded HARDIRQ variant.
