    xfs: define fatal assert build time tunable · 1040960e
    Brian Foster authored
    While configurable at runtime, the DEBUG mode assert failure
    behavior is usually either desired or not for a particular
    situation. For example, developers using kernel modules may prefer
    for fatal asserts to remain disabled across module reloads while QE
    engineers doing broad regression testing may prefer to have fatal
    asserts enabled on boot to facilitate data collection for bug
    To provide a compromise/convenience for developers, create a Kconfig
    option that sets the default value of the DEBUG mode 'bug_on_assert'
    sysfs tunable. The default behavior remains to trigger kernel BUGs
    on assert failures to preserve existing behavior across kernel
    configuration updates with DEBUG mode enabled.
