As others have noted, the msleep is potentially a crock.  However,
this particular patch is also incorrect - the *real* problem is
that the 4 line comment connected to the BUG_ON is mis-indented.

The patch *should* make it look like this:

	/* No pending activities shall be there on the vha now */
	if (ql2xextended_error_logging & ql_dbg_user)
		msleep(prandom_u32() % 10);
	/*
	 * Just to see if something falls on the net we have placed
	 * below
	 */
	BUG_ON(atomic_read(&vha->vref_count));

And a different patch should fix the msleep issue.
