Date: Mon, 20 Mar 2023 17:54:39 -0700 From: "Paul E. McKenney" <paulmck@...nel.org> To: linux-kernel@...r.kernel.org Cc: kernel-team@...a.com, rostedt@...dmis.org, jgross@...e.com, mingo@...nel.org, peterz@...radead.org, corbet@....net Subject: [PATCH RFC smp] Remove diagnostics and adjust config for CSD lock diagnostics Hello! This series removes CSD-lock diagnostics that were once very useful but which have not seen much action since. It also adjusts Kconfig and kernel-boot-parameter setup. 1. locking/csd_lock: Add Kconfig option for csd_debug default. 2. locking/csd_lock: Remove added data from CSD lock debugging. 3. locking/csd_lock: Remove per-CPU data indirection from CSD lock debugging. 4. kernel/smp: Make csdlock_debug= resettable. Thanx, Paul ------------------------------------------------------------------------ Documentation/admin-guide/kernel-parameters.txt | 17 - b/Documentation/admin-guide/kernel-parameters.txt | 6 b/kernel/smp.c | 2 b/lib/Kconfig.debug | 9 kernel/smp.c | 260 ++-------------------- 5 files changed, 47 insertions(+), 247 deletions(-)
