Documentation: preempt-locking: Use better example
The existing wording implies that the use of spin_unlock whilst irqs are disabled might trigger a reschedule. However the preemptible() test in preempt_schedule will prevent a reschedule if irqs are disabled. Lets improve the clarity of this wording to change the example from spin_unlock to cond_resched() and cond_resched_lock() as these are functions that will trigger a reschedule if the preempt count is 0 without testing that irqs are disabled. Also remove the 'Last Updated' line as this is not up to date and better tracked via GIT. Signed-off-by: Andrew Murray <andrew.murray@arm.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
