struct_ccw_device - channel attached device

SYNOPSIS

struct ccw_device {
  spinlock_t * ccwlock;

  struct ccw_driver * drv;
  struct device dev;
  int online;
  void (* handler) (struct ccw_device *, unsigned long, struct irb *);
};  

MEMBERS

ccwlock

id

id of this device

drv

ccw driver for this device

DESCRIPTION

handler is a member of the device rather than the driver since a driver can have different interrupt handlers for different ccw devices (multi-subchannel drivers).
