FLUSH_WORK(9) Driver Basics FLUSH_WORK(9)NAME
flush_work - block until a work_struct's callback has terminated
SYNOPSIS
int flush_work(struct work_struct * work);
ARGUMENTS
work
the work which is to be flushed
DESCRIPTION
Returns false if work has already terminated.
It is expected that, prior to calling flush_work, the caller has arranged for the work to not be requeued, otherwise it doesn't make sense
to use this function.
