Subject: [PATCH RFC smp] Remove diagnostics and adjust config for CSD lock diagnostics
Date: Mon, 20 Mar 2023 17:54:39 -0700 [thread overview]
Message-ID: <0c368b66-71b2-442f-a8f7-e6decc4be2d6@paulmck-laptop> (raw)
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
