General informations

• type: bool
• depends on: ( CONFIG_SMP || CONFIG_PREEMPT )
• defined in lib/Kconfig.debug
• found in Linux kernels: 2.6.37–2.6.38

Help text

This is the traditional lock that is used in old code instead of proper locking. All drivers that use the BKL should depend on this symbol. Say Y here unless you are working on removing the BKL.
