CONFIG_KCSAN_INTERRUPT_WATCHER: Interruptible watchers

General informations

The Linux kernel configuration item CONFIG_KCSAN_INTERRUPT_WATCHER:

• prompt: Interruptible watchers
• type: bool
• depends on: ! CONFIG_KCSAN_STRICT
• defined in lib/Kconfig.kcsan
• found in Linux kernels: 5.8–5.19, 6.0–6.8, 6.9-rc+HEAD

Help text

If enabled, a task that set up a watchpoint may be interrupted while delayed. This option will allow KCSAN to detect races between interrupted tasks and other threads of execution on the same CPU.

Currently disabled by default, because not all safe per-CPU access primitives and patterns may be accounted for, and therefore could result in false positives.
