NAME
       might_sleep - annotation for functions that can sleep

SYNOPSIS
       might_sleep(void);

ARGUMENTS
       None

DESCRIPTION
       this macro will print a stack trace if it is executed in an atomic
       context (spinlock, irq-handler, ...).

       This is a useful debugging help to be able to catch problems early and
       not be bitten later when the calling function happens to sleep when it
       is not supposed to.
