NAME
       work_busy - test whether a work is currently pending or running

SYNOPSIS
       unsigned int work_busy(struct work_struct * work);

ARGUMENTS
       work
	   the work to be tested

DESCRIPTION
       Test whether work is currently pending or running. There is no
       synchronization around this function and the test result is unreliable
       and only useful as advisory hints or for debugging. Especially for
       reentrant wqs, the pending state might hide the running state.

RETURNS
       OR´d bitmask of WORK_BUSY_* bits.
